Does the n = 0 make a difference since usually the questions have n = 1. Also for the ratio test since it
Just run the limit as it is shown.
So which formula is correct? The one you showed or the one i replied with?
You are correct. Sorry about that.
Ok, i'll give that a try then!
I got , so since we want to have series convergence, ? Since, series converges and , series diverges?
