# Find the sum of a series that is not a geometric or alternating series

Determine if the series converges or diverges. If it converges what does it converge to?

${\sum_{n=1}^\infty \frac{4}{n(n+3)}}$

Here's what I have been able to figure out

By the limit comparison test ${\sum\frac{1}{x^2}}$

${\lim_{x\to\infty}\frac{4n^2}{n^2 + 3n} = 4\Rightarrow}$ Convergence

But I can't figure out how to tell what it converges to, it's not an alternating series, or a geometric series that I can tell. And we haven't yet covered taylor series. It might be a power series, but I don't see any x value to tell what it converges to.
