see the attachment.

The given series is divergent because different values of a we get different limit therefore clearly divergent.

please see the attached image.

Ashwini , I have searched and come to conclusion that this sequence is convergent.. see my two attached - in first ( if a is non zero ) , in second ( if a is zero ) in both cas...

here a belongs to R is a constant , so for any value of a in R is convergent always..

any doubt then ask
