Divergence of a series given another divergence series

52 Views Asked by At

Honestly, It is a homework problem.

Let $\sum_{n=1}^{\infty} x_n$ be a divergent series with positive terms. We have to examine whether the following are true or false

i) $\sum_{n=1}^{\infty} \frac{x_n}{1+n^2x_n}$ is convergent

ii) $\sum_{n=1}^{\infty} \frac{x_n}{1+nx_n} $ is divergent

I am able to do the first one by comparing with the series $\sum_{n=1}^{\infty} \frac{1}{n^2} $

But the second one I am unable to do.

If $x_n$ $\geq$ $1$ then of course it is divergent. But in general I am unable to do it.

Please help.

I really do not want the full steps.

I just need a hint.

(I have tried by Comparison test or its limiting form)
