What is the average of the integers from 5 to 142? Here we will show you how to calculate the average of the integers from 5 to 142.
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 5 to 142, we need to divide the sum of the integers from 5 and 142 by the total number of integers from 5 to 142. Here are step-by-step instructions:
Step 1) Calculate Sum of Numbers
First, we calculate the sum of all the integers (whole numbers) from 5 to 142 by using a formula where a is the low number of 5 and b is the high number of 142:
Sum = ((b - a + 1) ÷ 2) × (a + b)
Sum = ((142 - 5 + 1) ÷ 2) × (5 + 142)
Sum = (138 ÷ 2) × (147)
Sum = 69 × 147
Sum of Numbers = 10143
Step 2) Calculate Total Number
Next, we calculate the total number of integers from 5 to 142. To calculate the total number of integers, we calculate the difference between 5 and 142 and then add 1. Here is the formula and the math. Once again, a is the low number of 5 and b is the high number of 142:
Total = b - a + 1
Total = 142 - 5 + 1
Total Number = 138
Step 3) Calculate the Average
Now we have both pieces needed to calculate the average of the integers from 5 to 142. 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 = 10143 ÷ 138
Average = 73.5
