What is the average of the first 28 multiples of 17?
Show answer & explanation
Correct answer: C
Explanation
Given:
The first 28 multiples of 17
According to the formula:
Average of the first n multiples = (First + Last) / 2
First = 17
Last = 17 × 28 = 476
Average = (17 + 476) / 2
= 493 / 2
= 246.5
