Find the average of first 125 natural numbers.

Question

Accepted Answer

The average of first n natural numbers is given by the formula: (Sum of first n natural numbers) / n. The sum of first n natural numbers is n(n+1)/2. For n = 125, sum = 125 × 126 / 2 = 7875. Therefore, average = 7875 / 125 = 63. However, since the average is the middle value in a sequence of consecutive numbers starting from 1, the average is (1 + 125) / 2 = 126 / 2 = 63. Both methods confirm the average is 63.
