Answer
$-18$, $7 - 5n$
Work Step by Step
Let $n$ be input and $y$ be output.
From the given table we notice that the pattern is the following:
$$y = 7-5n$$
We calculate the output for $n = 5$:
$$y=7-5(5)=-18$$
Now we complete the table:
\[
\begin{array}{|c|c|}
\hline
\textbf{Input} & \textbf{Output}\\ \hline
1& 2 \\ \hline
2 & -3\\ \hline
3 & -8 \\ \hline
4 & -13 \\ \hline
5 & -18 \\ \hline
: & : \\ \hline
n & 7-5n \\ \hline
\end{array}
\]
