To expand on Drexel's post a little, you have all the sums from 1 to . These are finite sums, so they all converge.
I think all the sums from 1 to . problem (a)(ii) using the ratio test, hence, this series converge.
I would consider that very ambiguous. What is shown as an upper limit is clearly " ", not " ". But without a definition of , the problems simply don't make sense!
