A series is conditionally covergent if and only if it is convergent but not absolutely convergent, i.e. we need to check weather this series is absolutely convergent or not to verify its conditional convergence. Here, in the given process it is not checked that this series is not absolutely convergent. Therefore, the given process is not sufficient for concluding that this series is a conditionally convergent.

Check if the following series converges absolutely, converges conditionally, or diverges. I know the series converges conditionally. This is determined by testing the series for "normal” convergence with the integral test, comparison test, root test or ratio test. If the series fails to be absolutely convergent the alternating series test is used in step 2. 2n + 3 Σ(-1)*. 3n2 +1 n=1
