Prime ={NPn*±IPn } i.e 30N±I5,
Prime Number range 5<=P<25,
I5 have 2 AP series with C.D=6, and first element = 5 & 7
5,11,17,23….infinite, C.D=6, T1=5
7,13,19,25…..infinite, C.D=6, T1=7
in example below you can see with help of I5 AP series we can find all Prime Number range 5<=P<25
P5*
I5
I5
Prime=(P5*-I5)
Prime= (I5-P5*)

You're thinking of the Sieve of Eratosthenes. I mean, you literally just stole the name, then replaced it with your own. Nothing you did was new.
To make matters worse, you clearly lack any meaningful understanding of the topic, because your writing is as rambly as mine is when I am writing and thinking about a brand new topic to myself. I literally did the same thing last night with regards to fundamental algebra, associativity, and commutativity.
The sieve, as you mentioned, is formed by starting with two, marking it as prime, and then marking all the integer multiples of two as not prime. Then you proceed to the next number that isn't marked, if no number below it multiplies by an integer to yield it, then it is prime, and you mark off all integer multiples of that, then proceed to the next unmarked number.
Following those steps, you get the primes 2, 3, 5, and 7 rather quickly, you immediately mark off all evens, multiples of three, five, and seven. To top it all off, as showcased in the first image on the wikipedia, by following those steps you've already found all primes up to 113, inclusive.
In addition, your statement that the composites are distributed "in the same way as primes", well, actually all composites are spread in the exact opposite manner, since primes become less dense as you go up the number line, then composites must necessarily become more dense. In other words, your description is patently, obviously, false.
In short, if you want to be taken seriously, proof read and google the hell out of your idea. If you think your idea is ground breaking, and you're not a professional mathematician on the bleeding edge of knowledge, it's probably not. God knows I've made that mistake plenty of times.
Thanks for reply plz find support of my post

There is definitely a reason why the composites seem to be distributed the same as primes in the original sieve. In particular, what you described as
If you examine your algorithm, you will see the list of composites in Prime2 are all numbers divisible by 2. This is obvious, of course.
All composites in your Prime3 as divisible by 3, but NOT by 2. All composites in your Prime5 list are divisible by 5, but not by 2 or 3.
Do you see what you are doing? You are simply filtering the set of integers for each subsequent iteration of the prime sieve, which artificially creates a sparser distribution for each subsequent prime sieve.
However, this uneven distribution does NOT match the distribution of primes in the original sieve. Whereas the original sieve results in an increasingly sparse distribution of primes, your sub-sieves necessarily have a repeating distribution because they are based on the fixed number of preceding primes.
For example, your Prime5 sieve shows composites divisible by 5 that are not divisible by 2 and 3. This means that these composites will simply start at 5*5 (25) and cycle every 30 integers (2*3*5). Thus: 25, 35, 55, 65, 85, 95, 115, 125, 145, etc. In other words, this distribution will not decrease in frequency like the prime sieve so therefore it is not the same.

ii) Continuous prime 5≤P<25

like this we can go for any series and any prime number.

I also posted the following in the sci.math newsgroup but got no responses that actually were interested in the main point of the "discovery" i thought i made.
would be happy if somewhere here could find the time to actually fill in the sieve of numbers as i am illustrating below:
Sieve of Vic?
I think i have discovered a more beautifull way to find the prime
numbers by using a Sieve. But i might be mistaken and have
rediscovered the wheel. My prime finding sieve method shows the
iterative nature of the primes very well and is therefore intriguing.
In short each primes causes an infinite number of other numbers to be
composite-numbers, but the composite numbers that are caused by each
prime are spread out in the exact same pattern as the primes
themselves are spread out.
I am not a mathimatican so please bare with me while I illustrate by
example instead of by formula. I would appreciate any serious
feedback. It might be I re-invented the wheel. I dont know. I dont do
maths often. only have been looking at primes as a sudoko puzzle. But
i thought i might actually have stumbled on an original thought. Hence
this post.
I am using a sieve approach for finding prime numbers. Just like
Eratosthenes. Noting all the numbers on a big sheet starting with 2
and numbering to however much you like.
Number 2 is the first prime in my mind. I note it on the primelist.
For every prime i find i have to cross out its power. 2 * 2 = 4. I
make a note on 4 that its the 1st composite-number caused by prime2.
Number 3 is not crossed out so its a prime. I note it on the
primelist. I now also cross out its power. 3*3=9. I make a note on 9
that its the 1st composite-number caused by prime3.
Number 4 is crossed out so its not a prime. Prime2 however left off
here. The pattern of prime 2 can now also be established. Its size is
1 because its the first pattern defined and its only pattern slot is 1
too. 1 because thats the difference between the first prime (2) and
the next (3). Knowing this pattern i know now the 2nd composite-number
caused by 2 must be current number(4) + (slot value(1) * prime(2)) =
6. I make a note on 6 that its the 2nd composite number caused by
prime2.
Number 5 is not crossed out so its a prime. I note it on the
primelist. I now also cross out its power 5*5 =25. I make a note on 25
that its the 1st composite-number caused by prime5.
Number 6 is crossed out so its not a prime. Prime2 however left off
here. Knowing this pattern i know now the 3rd composite-number caused
by 2 must be current number(6) + (slot value(1) * prime(2)) = 8. I
make a note on 8 that its the 3rd composite number caused by prime2.
Number 7 is not crossed out so its a prime. I note it on the
primelist. I now also cross out its power 7*7 =49. I make a note on 49
that its the 1st composite-number caused by prime7.
Number 8 is crossed out so its not a prime. Prime2 however left off
here. Knowing this pattern i know now the 4th composite-number caused
by 2 must be current number(8) + (slot value(1) * prime(2)) = 10. I
make a note on 10 that its the 4th composite number caused by prime2.
Number 9 is crossed out so its not a prime. Prime3 however left off
here. The pattern of prime 3 can now also be established. Its size is
1 because its the second pattern defined and its only pattern slot is
2. 2 because thats the difference between the second prime (3) and the
next (5).
Knowing this pattern i know now the 2nd composite-number caused by 3
must be current number(9) + (slot value(2) * prime(3)) = 15. I make a
note on 15 that its the 2nd compositie number caused by prime3.
Number 10 is crossed out so its not a prime. Prime2 however left off
here. Knowing this pattern i know now the 5th composite-number caused
by 2 must be current number(10) + (slot value(1) * prime(2)) = 12. I
make a note on 12 that its the 5th composite number caused by prime2.
Number 11 is not crossed out so its a prime. I note it on the
primelist. I now also cross out its power 11*11 =121. I make a note on
121 that its the 1st composite-number caused by prime11.
Number 12 is crossed out so its not a prime. Prime2 however left off
here. Knowing this pattern i know now the 5th composite-number caused
by 2 must be current number(12) + (slot value(1) * prime(2)) = 14. I
make a note on 14 that its the 6th composite number caused by prime2.
etc... etc... for number 13 and number 14
Number 15 is crossed out so its not a prime. Prime3 however left off
here. Knowing this pattern i know now the 3rd composite-number caused
by 3 must be current number(15) + (slot value(2) * prime(3)) = 21. I
make a note on 21 that its the 3rd compositie number caused by prime3.
..etc.. etc..
Number 25 is crossed out so its not a prime. Prime5 however left off
here. The pattern of prime 5 can now also be established. Its size is
2 because its the third pattern defined and its pattern size is 2 with
the pattern slots being [2, 4] because thats respectivly the
difference between the third prime (5) and the next (7) and the next
one(7) and the next-next one(11).
Knowing this pattern i know now the 3rd composite-number caused by 5
must be current number(25) + (slot value(2) * prime(5)) = 25. I make a
note on 35 that its the 2nd compositie number caused by prime5.
etc.. etc...
Number 35 is crossed out so its not a prime. Prime5 however left off
here. Knowing this pattern i know now the 4th composite-number caused
by 5 must be current number(35) + (slot value(4) * prime(5)) = 55. I
make a note on 55 that its the 4th compositie number caused by prime5.
etc..
Number 55 is crossed out so its not a prime. Prime5 however left off
here. Knowing this pattern i know now the 5th composite-number caused
by 5 must be current number(55) + (slot value(2) * prime(5)) = 65.
Since this the third slot value we have look up for 5 and the pattern
size was only 2 we return here to slot 1. I make a note on 65 that its
the 5th compositie number caused by prime5.
etc..
ad infinitum...
TABLE OF PATTERN SIZE
Prime2 = 1
Prime3 = 1 (1*1)
Prime5 = 2 ( 2*1)
Prime 7 = 8 (4*2)
Prime 11= 48 (6*8)
Prime 13 = 480 (10*48)
Prime 17= 5760 (12*480)
Prime 19 = 92160 (16*5760)
Next pattern size is thus based on the ((current prime - 1 ) *
current pattern size)
TABLE OF SLOT VALUES OF PATTERNS
Number 2. [ 1 ]
Number 3. [ 2 ]
Number 5. [ 2, 4 ]
Number 7. [ 4, 2, 4, 2, 4, 6, 2, 6 ] (8 numbers)
Number 11. [ 2, 4, 2, 4, 6, ... ] (48 numbers)
Number 13. [ 4, 2, 4, 6, .. ] (480 numbers)
TABLE OF COMPOSITE NUMBERS CREATED BY PRIMES
Prime2 : 4,6,8,10,12,14,etc..
Prime3 : 9,15,21,27,33,etc...
Prime5: 25,35,55,65,85,95,115,125,etc...
Prime7: 49,77,91,119,etc...

Me to intruded same funda for prime number find out
with mod 3#,5#,7#,11#
3#=6 gives all prime 3>=p<9
5#=30 gives all all prime 5>=p<=25
7#=210 gives all prime 7>=p<=49
11#=2310 gives all prime 11>=p<=121
.
.
.
.
Pn#=...gives all prime Pn#>=p<=(Pn)^2
so we can find out any prime number in any range.Only thing is that i have required more advance compute which is comfortable with large numbers.

Is it possible to find all consecutive prime in fix range ? .
in Applied Mathematics
Posted
Bcz we can find out any consecutive prime number by just subtraction of two numbers of series i.e Pn*, and Ipn.
