The below workout with step by step calculation shows how to find what is the average of numbers from 50 to 75 manually.
step 1 Address the formula and input values.
Formula: Average = Total Sum of Numbers / Total Count of Numbers
Input values:
The numbers from 50 to 75 are
50, 51, 52, 53, . . . . , 73, 74, 75
Total Count of Numbers = 26
step 2 Find the sum of numbers from 50 to 75.
sum = 50 + 51 + 52 + . . . . + 74 + 75
= 1625
step 3 Divide the sum by 26
Average = 1625/26
= 62.5
62.5 is an average of numbers from 50 to 75.
