Answer:
a.Converge
b.Diverge
Step-by-step explanation:
We are given that



Because 
Hence, sequence An converges to
when n tends to infinity or - infinity.
=diverges
Necessary condition for a series to converge :
when n tends to infinity .
But
tends to
when n tends to infinity.
Therefore, given series is divergent.
