Question

((-1)^n*n)/(3+2n^2), this series converges, but i cant quite find the limit. need to find the limit

Answer 1

pretty sure limit is 0

(-1)^n simply alternates between 1 and -1
\[\lim_{n \rightarrow \infty} \frac{n}{3+2n^2} = 0\]

Answer 2

are you really trying to find the limit of series ? @acal21

Answer 3

By alternating series test, the series converges. I'm not sure if you really want to find the sum

Answer 4

YES CAUSE THIS SERIES CONVERGES , THE PROBLEMS ASK ME TO FIND THE LIMIT IF IT CONVERGES
