Given information
Given alternate series
Step-by-step explanation
Step 1.
Observe that a series is called absolutely convergent if the series of absolute values is convergent.
Take the sequence of a partial fraction of the alternate series is
Since
Therefore
Observe that here is a geometric series with
Here, common ratio , so the is convergent
Hence, is absolutely convergent
