A sequence
is monotonic if its terms are non decreasing
or if its terms are non increasing
.
The terms in the sequence are
.
Therefore, the sequence is monotonic.
\The sequence is
.
The terms in the sequence are
.
The terms in the sequence are increase with out bound.
\The sequence is not bounded.
\Graph the sequence

Observe the graph:
\The sequence is increasing and it is monotonic.
\The sequence is not bounded.
\The sequence is monotonic and not bounded.
