Question:

The sum of 7 numbers is greater than 140 and less than 210. Which of the following could be the average (arithmetic mean) of the numbers?

A 26
explanation

The formula for the average of a set of numbers is the sum of the numbers divided by the number of terms.
Avg = 140 ÷ 7
Avg = 20
Avg = 210 ÷ 7
Avg = 30
Therefore, the average must be between 20 and 30.
