# Homework Help: Convergence of a factorial function

1. Sep 23, 2012

The sum of "(n+3)!/(3n+2)!" with n=1 to n=inf. How do I find if it converges or diverges by using one of the tests(ratio, roots series, divergence, etc)?

Well, you have a ratio, so the ratio test seems worth trying. Did you try it?
