##### Solution Preview

This series diverges. You can tell by using the "integral test", which states

sum from k =1 to infinity of f(k) converges if and only if

the integral from q to infinity of f(x)dx converges

for x >= q >= 1

The integral of (2x + 1) / (x^2 + 1) can be broken into the sum of ...
