Step-by-step explanation:
If you want the explanation just tell me
I'm going to assume you meant to write fractions (because if
are all non-negative integers, the series would clearly diverge), so that



and so on.
a. If the pattern continues as above, we would have the general term

b. Note that we can write
as

The series diverges by comparison to the divergent series
