If it converges find the limit and if it diverges justify why.
Thanks for the replies. I understand the sequence definitely diverges.
Please note my brother asked me this question and it is not part of my coursework(and i have never done anything like this before), which is why i didn't make an attempt at a solution, however i am still interested in the answer.
His question asked to find an appropriate epsilon and n to justify why the series diverges.
