Question

the average of even numbers between 21 and 29

Answer 1

List the even number between 21 and 29:

Even numbers = 22, 24, 26, 28

Find the sum of these numbers:

Sum = 22 + 24 + 26 + 28 = 100

Find the average of these numbers:

Average = Sum ÷ Number of terms

Average = 100 ÷ 4 = 25

Answer: The average is 25

Answer 2

The total number of observations between 21 and 29 are 22, 24, 26 and 28

Hence, the total number of observations are four.

Average = sum of all the observation/ total number of observations

Average = 22 + 24 + 26 + 28 / 4

Average = 100/4

Average = 25

Hence the answer will be 25.
