RE: Riddles, brain puzzles and mathematical problems

Hint: Don't use mathematical induction. You can probably solve it, but it's way harder (+ there could be some flaws in your logic if you aren't careful because you aren't trying to prove something like (prove 1+2+3+..+n = n*(n+1)/2), but you want to prove that A is integer when n is odd). Try writing 1 + 1/n as (n+1)/n
The answer is 2 lines long (depends on how you write of course). With induction (as you saw) it already became complicated.

•I have found the answer to the universe and everything, but this sign is too small to contain it.
