c. the series diverges.
d. the alternating series test shows the series converges.
e. the series is a p-series. f. the series is a geometric series. g. we can decide whether this series converges by comparison with a p series. h. we can decide whether this series converges by comparison with a geometric series. i. partial sums of the series telescope. j. the terms of the series do not have limit zero. a 1. \displaystyle \sum^\infty_{n=1} \left( 1 + \frac{5 }{n} \right)^n

\displaystyle\sum_(n=1)^\infty\left(1+\frac5n\right)^n

Notice that


\displaystyle\lim_(n\to\infty)\left(1+\frac5n\right)^n=e^5\\eq0

which means the series is divergent. So if this is one of those "select all that apply" questions, then both (c) and (j) are the only choices that do.
