Average of consecutive natural numbers from 20 to ‘N’ is 44. What is the value of N? (where N is a natural number)
Show answer & explanation
Correct answer: C
Explanation
Given:
Average of numbers from 20 to N = 44
According to the formula:
Average = (First + Last) / 2
(20 + N) / 2 = 44
20 + N = 88
N = 68
