What is the average of the integers from 3 to 39? Here we will show you how to calculate the average of the integers from 3 to 39.
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 3 to 39, we need to divide the sum of the integers from 3 and 39 by the total number of integers from 3 to 39. Here are step-by-step instructions:
Step 1) Calculate Sum of Numbers
First, we calculate the sum of all the integers (whole numbers) from 3 to 39 by using a formula where a is the low number of 3 and b is the high number of 39:
Sum = ((b - a + 1) ÷ 2) × (a + b)
Sum = ((39 - 3 + 1) ÷ 2) × (3 + 39)
Sum = (37 ÷ 2) × (42)
Sum = 18.5 × 42
Sum of Numbers = 777
Step 2) Calculate Total Number
Next, we calculate the total number of integers from 3 to 39. To calculate the total number of integers, we calculate the difference between 3 and 39 and then add 1. Here is the formula and the math. Once again, a is the low number of 3 and b is the high number of 39:
Total = b - a + 1
Total = 39 - 3 + 1
Total Number = 37
Step 3) Calculate the Average
Now we have both pieces needed to calculate the average of the integers from 3 to 39. 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 = 777 ÷ 37
Average = 21
