What is the average of the integers from 145 to 171? Here we will show you how to calculate the average of the integers from 145 to 171.
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 145 to 171, we need to divide the sum of the integers from 145 and 171 by the total number of integers from 145 to 171. Here are step-by-step instructions:
Step 1) Calculate Sum of Numbers
First, we calculate the sum of all the integers (whole numbers) from 145 to 171 by using a formula where a is the low number of 145 and b is the high number of 171:
Sum = ((b - a + 1) ÷ 2) × (a + b)
Sum = ((171 - 145 + 1) ÷ 2) × (145 + 171)
Sum = (27 ÷ 2) × (316)
Sum = 13.5 × 316
Sum of Numbers = 4266
Step 2) Calculate Total Number
Next, we calculate the total number of integers from 145 to 171. To calculate the total number of integers, we calculate the difference between 145 and 171 and then add 1. Here is the formula and the math. Once again, a is the low number of 145 and b is the high number of 171:
Total = b - a + 1
Total = 171 - 145 + 1
Total Number = 27
Step 3) Calculate the Average
Now we have both pieces needed to calculate the average of the integers from 145 to 171. 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 = 4266 ÷ 27
Average = 158
