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

\[\Big |A_{n}-A_{n-1}\Big|\geq C \space for \space some \space C \space >0; n\space \epsilon \space N\] <<--- Is this the formula? (Right click to see the TeX code.) I too rusty to help with this but I wanted to practice the LaTeX system.

yes it is. An is a sequence in R

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??

OK - that _is_ an absolute value symbol right? I'm stumped, frankly I'm a bit rusty and the absolute value symbols are confusing me. Try posting this again in a new question. Sometimes folks only open questions with no replies.
