A table of values of a linear function is shown below. Find the output when the input is n?

 

1234n
-11-14-17-20-8-3n

 

\(\begin{array}{|rcll|} \hline \mathbf{a_n} &=& \mathbf{a_1+(n-1)d} \quad | \quad a_1 = -11,\ d=-3 \\\\ a_n &=&-11+(n-1)*(-3) \\ a_n &=&-11-3n+3 \\ \mathbf{a_n} &=& \mathbf{-8-3n} \\ \hline \end{array}\)
