I'm pretty embarassed that with a math degree I don't know how to do this. But today someone asked me to help him test this series for convergence:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\Sigma \, ln(\dfrac{(k+1)^{2}}{k(k+2)} )[/tex]

Maybe I'm just having a brain fart, but I can't think of any series to compare this to, and I obviously can't use the ratio, root, or integral tests. Any suggestions?
