I need some help finding the sum of this and showing it converges. To show a series is convergent do you show its limit approaches zero? So for a divergent series you would show it doesn't approach zero.

No, the test is inconclusive when the limit of the summand is zero (eg. the series can converge or diverge). Try the ratio test.
