To find the average (mean) of numbers, we add the numbers and then divide the sum by the number of terms added. For example, to find the average of $14,8,3,9,$ and $1,$ we add them and then divide by 5. $$ \frac{14+8+3+9+1}{5}=\frac{35}{5}=7 \leftarrow \text { Average } $$ Find the average of each group of numbers. All even integers between $-18$ and $4,$ inclusive
