What is the average of the integers from 17 to 119? Here we will show you how to calculate the average of the integers from 17 to 119.
To calculate the average of any set of numbers, you divide the sum of the numbers by the total numbers in the set (Sum/Total).
Therefore, to calculate the average of the integers from 17 to 119, we need to divide the sum of the integers from 17 and 119 by the total number of integers from 17 to 119. Here are step-by-step instructions:
Step 1) Calculate Sum of Numbers
First, we calculate the sum of all the integers (whole numbers) from 17 to 119 by using a formula where a is the low number of 17 and b is the high number of 119:
Sum = ((b - a + 1) ÷ 2) × (a + b)
Sum = ((119 - 17 + 1) ÷ 2) × (17 + 119)
Sum = (103 ÷ 2) × (136)
Sum = 51.5 × 136
Sum of Numbers = 7004
Step 2) Calculate Total Number
Next, we calculate the total number of integers from 17 to 119. To calculate the total number of integers, we calculate the difference between 17 and 119 and then add 1. Here is the formula and the math. Once again, a is the low number of 17 and b is the high number of 119:
Total = b - a + 1
Total = 119 - 17 + 1
Total Number = 103
Step 3) Calculate the Average
Now we have both pieces needed to calculate the average of the integers from 17 to 119. We calculate the average of the integers by dividing the Sum of Numbers from Step 1 by the Total Number from Step 2. Here is the math and the answer:
Average = Sum of Numbers ÷ Total Number
Average = 7004 ÷ 103
Average = 68
