(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A_{n}= (((-1)^(n-1))n)/(n^2 + 1)

I need to know if it converges or diverges and if it converges the limit.

2. Relevant equations

3. The attempt at a solution

I know it converges to 0. But I don't know how to show it when evaluating. I tried evaluation A_{n}| in the absolute value but I keep ending up with oo/oo
