Average is the sum divided by the count. Therefore** the sum is the average times the count**

There is a total of 16 students.

The average of 14 students is 92. => The total score of the 14 students is 1288 = 92X14.

The 15th student got 71. => The total score of 15 students is 1359= 1288+71

The average of 16 students is 88 => The total score of all the 16 students is 1408= 88x16

What is the score of the last student who took the quiz?

The total score of 16 students - The total score of 15 students is the answer.
