The below workout with step by step calculation shows how to find what is the average of numbers from 50 to 100 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 100 are
50, 51, 52, 53, . . . . , 98, 99, 100
Total Count of Numbers = 51
step 2 Find the sum of numbers from 50 to 100.
sum = 50 + 51 + 52 + . . . . + 99 + 100
= 3825
step 3 Divide the sum by 51
Average = 3825/51
= 75
75 is an average of numbers from 50 to 100.
