Is it possible for someone to fully breakdown this series question? Thank you

For each of the following series, state whether they are absolutely convergent, conditionally convergent, or divergent. Name a test which supports each conclusion and show the work to apply the test. (-1)n (-3)n + 1/22n (-1)n (n3 - 6n)/8n3 + 1

Solution

a) r = |(-3/4)| < 1 So it is convergent. Ratio test b) r = 1/8 < 1. So it is convergent. Ratio test
