fantastic ! impressive . huge THANK

sure but what if you were asked to derive f(m) from scratch ?

oh sure ! (n^3)/(2^n)

n^3 a classic 2^n not to mention but combined ?

next week i should undergo endoscopy .

yep pilori looms as a mighty candidate. and he sphincter !

otherwise my weight has been stable as an adult

according to the source* , this expression f(m) is a fact one "notices" in order to get the value for m infinite ...... which is 26 !

ok thank you so much for your input .

zero coughing, zero irritations

just the onset of heartburn and the urge to let the gas out which entails very deep and relentless pig reminiscent belching.

i dont drink with the meals.

coffe seems to be a trigger , but somewhat dependent on stomach content.

for decades i have been a victim of heatburn accompanied by severe belching (burping)

after certain types of food's ingestion.

what gas is created in the stomach and how ?

obviously we are not looking at small intestine fauna fermenting fibre .....

my gratitude is ou there to the solver of a lifelong riddle

sorry for an unforgivable typo !!!!

n^3/2^n .

but even this answer was helpful. sum of the powers must be the next power , seems logical , is there a proof ?

fantastic , (n(n+1))^2 / 4 is a polynome of deg 4 indeed.

from a high school level math book "les math au carré" by M-P. Falissard , page 133

n integer

she uses the expression to deduce the limit of the sum as m approaches infinity (26)

my gratitude to any solid help on this one !
