Let $\{x_n\}$ be a sequence of real numbers and let $y_n = \max \{x_1, x_2, \ldots , x_n\}$ for each positive integer $n$.
Give an example of an unbounded sequence {$x_n$} for which {$y_n$} converges.
I understand this conceptually but having a difficult time finding such a sequence. Any help would be appreciated!
