the question is: determine whether the series is absolutely convergent, conditionally convergent or divergent.

$\displaystyle \sum_{n = 1}^{\infty} (-3)^n \frac{n+1}{\exp(n)}$

I found that if i do the ratio test it diverges but im not sure how to do the alternating test, is a just

$\displaystyle \frac{n+1}{\exp(n)}$

or does it include the 3?
