## Homework Statement

Determine whether the sequence a

_{n}= 1

^{1}/n

^{2}= 2

^{1}/n

^{2}+ ... + n

^{1}/n

^{2}converges or diverges. If it converges, find the limit.

**2. The attempt at a solution**

I have no idea what to do with this problem. I don't see why I can't simplify n/n^2 to 1/n. It was suggested to me to factor out 1/n and introduce the variable i (from Riemann Sums), but I don't see how that helps (and I don't see how I would just introduce i anyway).
