Best ResponseYou've already chosen the best response.1Since it converges, you have that for all \(\epsilon>0\), \(La_n<\epsilon\) for all \(n>N\) for some \(N\in\mathbb{N}\). Now, we guess that \(\{a_n+1\}\) converges to \(L+1\). Look at \(L+1(a_n+1)\). What can you say about it?

Best ResponseYou've already chosen the best response.0It's a with subscript (n+1) . I'm ask confused with your symbols

Best ResponseYou've already chosen the best response.1Ah. So your new sequence is \(\{a_{n+1}\}\)?

Best ResponseYou've already chosen the best response.0Hey, @kimmy0394 When you think about it \[\huge a_{n+1}\]is just the same sequence, just that it starts one step ahead of \[\huge a_n\] right?
