The below workout with step by step calculation shows how to find what is the average of numbers from 25 to 50 manually.
step 1 Address the formula and input values.
Formula: Average = Total Sum of Numbers / Total Count of Numbers
Input values:
The numbers from 25 to 50 are
25, 26, 27, 28, . . . . , 48, 49, 50
Total Count of Numbers = 26
step 2 Find the sum of numbers from 25 to 50.
sum = 25 + 26 + 27 + . . . . + 49 + 50
= 975
step 3 Divide the sum by 26
Average = 975/26
= 37.5
37.5 is an average of numbers from 25 to 50.
