The below workout with step by step calculation shows how to find what is the average of numbers from 500 to 1000 manually.
step 1 Address the formula and input values.
Formula: Average = Total Sum of Numbers / Total Count of Numbers
Input values:
The numbers from 500 to 1000 are
500, 501, 502, 503, . . . . , 998, 999, 1000
Total Count of Numbers = 501
step 2 Find the sum of numbers from 500 to 1000.
sum = 500 + 501 + 502 + . . . . + 999 + 1000
= 375750
step 3 Divide the sum by 501
Average = 375750/501
= 750
750 is an average of numbers from 500 to 1000.
