You have a variable scope problem in your problem statement. Once the sum has occurred, there is no n left in the expression. Thus, the limit basically does nothing. Did you mean to use a dummy variable for the sum, and sum, say, from j = 1 to n?
i tried to look for collapsing fractions but they don't collapse
i tried to find the limit of the ratio of
but i don't know how to begin untangling that thing
is there another way or can you tell me how to begin to figure something out of that?

Why have you been asked to discuses series convergence when it is perfectly clear that you are missing the very basic ideas??
Has your text/instructor discussed the harmonic series?
If so what are the basics there?
How does that apply here?
If not, then you are not ready to do this question.
i haven't been asked to do anything, i'm doing this on my own to prepare for the university
i have a book for calculus1 and i have recorded video lectures, but i guess it doesn't cover everything because there was nothing specific about harmonic series either in the book or the lectures.. do you know anything online that you can recommend on the subject?
how much am i missing here?
