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 ...
The solution solves for convergence or divergence, absolute or conditional of a summation.
