Question

Anyone know proofs?

Answer 1

thats hard

Answer 2

seems darned unlikely

Answer 3

Hard indeed

Answer 4

since if
\[\sum a_n\] converges then we know for sure that
\[\lim_{n\to \infty}a_n=0\]

Answer 5

and therefore
\[\lim_{n \to \infty}\frac{1}{1+a_n}=1\]

Answer 6

so since the individual terms do not go to 0, it is impossible for the sum to be finite

Answer 7

can someone give me a medal plz
