Find the average of the first fifteen multiples of 11.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 88.

Thus, the average of all these terms would be the middle terms when these terms are arranged in ascending order.
Thus, the 8th term would be the average of all these terms.
8th term is 88 which is 8th multiple of 11
