The average of the integers from 3 to 19
What is the average of the integers from 3 to 19? Here we will show you how to calculate the average of the integers from 3 to 19.
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 19, we need to divide the sum of the integers from 3 and 19 by the total number of integers from 3 to 19. 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 19 by using a formula where a is the low number of 3 and b is the high number of 19:
Sum = ((b - a + 1) ÷ 2) × (a + b)
Sum = ((19 - 3 + 1) ÷ 2) × (3 + 19)
Sum = (17 ÷ 2) × (22)
Sum = 8.5 × 22
Sum of Numbers = 187
Step 2) Calculate Total Number
Next, we calculate the total number of integers from 3 to 19. To calculate the total number of integers, we calculate the difference between 3 and 19 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 19:
Total = b - a + 1
Total = 19 - 3 + 1
Total Number = 17
Step 3) Calculate the Average
Now we have both pieces needed to calculate the average of the integers from 3 to 19. 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 = 187 ÷ 17
Average = 11
