What is the average of 5 10 15?
Average(5, 10, 15) = (5 + 10 + 15)/3 = 30/3 = 10
What is the average of 15 30 45?
To find the average of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, the sum of 15, 30, and 45 is 90. Since there are three numbers in the set, you divide 90 by 3 to get an average of 30.

How do you use number line to calculate the average of two different averages?
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.
