Determine whether the series converges or diverges.
What I would like is some type of information on how to continue the problem.
The Attempt at a Solution
I was thinking of doing a comparison test by doing
√(n+1)/2n^2+n+1 < √(n+1)/2n^2 or √(n+1)/2n^2+n+1 < 2n(n+1)
After that, I end up being stumped by the problem.
