Answer:
Series is divergent .
Step-by-step explanation:
Here nth term of the given series is

Let the given series be 

Let
= 
on simplifying it ,we get
limit of the ratio = 5 (which is finite and nonzero)
therefore using comparison test both an and bn converge or diverge together .
for bn =
is a geometric series with
common ratio
>1
therefore for bn series is divergent.
therefore an also divergent ( using comparison test)
