What is the average of the following marks: 78, 92, 85, 77, 90?

Explanation:
Average is found by adding all the values and dividing by how many values there are. For these marks: 78 + 92 + 85 + 77 + 90 equals 422. There are 5 numbers, so 422 ÷ 5 = 84.4. Therefore, the average is 84.4, which sits between the lowest and highest marks (77 and 92) as a quick check.
