Series convergence/ divergence


Determine whether the following series is absolutely convergent, conditionally convergent or divergent.

$$\sum_{n=1}^\infty(-0.75)^n\dfrac{n+1}{2}$$




I tried using the divergence test and the alternating series test but I can't seem to use it or this problem as I could not take the limit of the function.
