\

The sequence is $\"\"$ .

\

A sequence $\"\"$ is monotonic if its terms are non decreasing $\"\"$ or if its terms are non increasing $\"\"$ .

\

The terms in the sequence are first increase and then it is decreasing.

\

Therefore, the sequence is not monotonic.

Graph the sequence $\"\"$ .

$\"\"$

\

Observe the graph:

\

The terms in the sequence are first increasing and then decreasing.

\

The sequence is not monotonic.

\

The sequence is bounded between $\"\"$ to $\"\"$ .

\

$\"\"$

\

The sequence is not monotonic but bounded.
