# Math Help - Sequences and Series

1. ## Sequences and Series

Hey I'm in my 2nd year of calculus and we no longer do sequences and series, I had a friend of mine ask me about a question he had, and tried to work out and ended up not getting it completely and handing it in partially completed for some marks, he got me thinking and these are the two questions he had trouble with, can anyone shed some light on them for me to relay back to him. Thanks.

Determine if the sequence is convergent or divergent, if convergent what does it converge to?

$\{\frac{(\ln (n))^3}{n^2}\}$ $\{(3(n^2) + 1)^(2/n)\}$
