Answer: 16
Step-by-step explanation:
To find the average, you want to take the sum of all the numbers and divide by the amount of numbers.
[tex]\frac{11+13+18+22}{4} =\frac{64}{4} =16[/tex]
After we add 11, 13, 18, 22, we get 64. There are 4 total numbers. Therefore, we divide 64 by 4. We get the answer 16.
