Hi all,

 

Just a few primitive teasers to occupy your mind with. Find a way to generate these sequences:

 

1. 1, 2, 4, 8, 16, 32, 64...

2. 0, 1, 1, 2, 3, 5, 8, 13...

3. 3, 1, 4, 1, 5, 9, 2, 6...

And one that's a little harder:

 

4. 1, 2, 2, 3, 4, 3, 5, 4, 6, 7, 5, 3...

 

Enjoy,

 

Gabe

1. 1, 2, 4, 8, 16, 32, 64...

[hide][math]2^n[/math][/hide]

 

2. 0, 1, 1, 2, 3, 5, 8, 13...

[hide]Fibonacci sequence, sum of previous two terms[/hide]

 

3. 3, 1, 4, 1, 5, 9, 2, 6...

[hide]Very cute -- digits of pi[/hide]

 

4. 1, 2, 2, 3, 4, 3, 5, 4, 6, 7, 5, 3...

[hide]Have to go, will do this later[/hide]

Nice, although not surprised you got them ) Have a look at that last one...

 

Cheers,

Here's another one, however this one is with letters:

 

5. Q, A, Z, W, S...

 

Just to have it written down, numbers 4. and 5. have yet to be solved...so good luck, you won't be needing it )

 

Cheers,

 

Gabe

5. Q, A, Z, W, S...

[hide]Looks like the letters on the keyboard. Q,A,Z,W,S,X,E,D,C...[/hide]

How about this?

 

 6. 12243 64860 72849 6...

 

How is 4. coming along? Any luck? That's a pretty tough one, I admit.

 

Cheers,

 

Gabe

arrrg.. ye am trying to solve that #4 pffff

 

annoyed ^^

:-D I'll be honest with you, if you solve that one I'll be the happiest person on the planet...

Hard.
