Question

Calculate the limit sequence.

Answer 1

\[a _{n}=2+\frac{ (-1)^n }{ n }\]

Answer 2

\[\lim_{n \rightarrow \infty}(2+\frac{ (-1)^n }{ n })=\lim_{n \rightarrow \infty}2+\lim_{n \rightarrow \infty}\frac{ (-1)^n }{ n }\]
How would I solve for \[\lim_{n \rightarrow \infty}\frac{ (-1)^n }{ n }\]?
