Ok so I am a little stuck on this question, I need to test this series using only the standard comparison test.
I can't compare it to can I?

Since , you can compare this series to . If you use partial fractions, you should find that this series is telescopic...
Thanks, also what about
I would use the integral test, because I can see that is easily evaluated. .
So the series is divergent.

We can't unfortunately. Only the comparison test and the arithmetic, geometric, harmonic series and series.
I let n= and got
which is geometric and converges. But I'm not at all confident with that.
Ok that gives me something to go off I will try and figure out to see if I can show it is divergent somehow
Ok I think I got it. which diverges so must diverge.
Does this sound right?
Ho do you know that ?
OK I agree with your comparison then
Thanks a lot you were a real help
