If |An - An+1)|>=C for some C>0 and n is an element of N, prove that the sequence An diverges. Noted n and and n+1is subscript. Can anybody help me out??
Looks like a proof to me, and that's usually alot of work when it comes to infinite series, I could try and help you if you give me the name of the proof/theorem. How much have you done so far? What steps are unclear for you?
