 Therefore, the sequence is not monotonic because it is both increasing and decreasing. We can express this in LaTeX as follows:
 
-$a_n=n^{2}-8n+15$ is not monotonic because its first derivative, $a'_n=2n-8$, has both positive and negative values.
+$a_n=n^{2}-8n+15$ is not monotonic because its first derivative, $a'_n=2n-8$, has both positive and negative values.

+where $U$ is the internal energy of the gas, $P$ is the pressure of the gas, and $V$ is the volume of the gas. This equation describes the change in the internal energy of the gas as it expands adiabatically, which means that there is no heat transfer between the gas and its surroundings.
