ANSWER:
27
STEP-BY-STEP EXPLANATION:
The first thing is to determine the pattern that the table follows, we will do this by calculating the ratio between the output values and input values, like this:
[tex]\begin{gathered} r=\frac{-9}{-1}=9 \\ r=\frac{9}{1}=9 \\ r=\frac{18}{2}=9 \\ r=\frac{36}{4}=9 \end{gathered}[/tex]Therefore, the ratio is 9, the value of n would be:
[tex]\begin{gathered} \frac{n}{3}=9 \\ n=9\cdot3 \\ n=27 \end{gathered}[/tex]
