test for convergence/divergence
i'm just not sure where to startplease help!
If the two series on the right are convergent, then so is the one on the left. The right-most series is clearly geometric, so it's just the left series on the RHS we have to deal with.
If you know the ratio test, you can use it to find that converges.
If you haven't learned it yet, use the identity: for all and use comparison.
i'm just wondering..does it make any difference that the series that i posted started at n=1 and you're using n=0?
also, is there anyway that you could kind of show me how the ratio test works here? i just learned it and i'm a little unsure of myself
