Formula: Average = Total Sum of Numbers / Total Count of Numbers
The numbers from 20 to 80 are
20, 21, 22, 23, . . . . , 78, 79, 80
Total Count of Numbers = 61
step 2 Find the sum of numbers from 20 to 80.
sum = 20 + 21 + 22 + . . . . + 79 + 80
= 3050
step 3 Divide the sum by 61 Average = 3050/61 = 50
Thus, 50 is an average of numbers from 20 to 80.
