What is the average of even numbers from 55 to 150? Here we will show you how to calculate the average of even numbers from 55 to 150.
To find the average of the even numbers from 55 to 150, we first calculate how many even numbers there are from 55 to 150. Then, we calculate the sum of even numbers from 55 to 150. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 55 to 150, and the even numbers within that range are from 56 to 150. Therefore, the first even number in the sequence is 56, and the last even number in the sequence is 150.
Step 1) Calculate the total number of even numbers from 55 to 150
Here we calculate the total number of even numbers from 55 to 150 by entering the first and last even number in the sequence into our formula. Here is the formula and the math:
tot = (last - first + 2) ÷ 2
tot = (150 - 56 + 2) ÷ 2
tot = 96 ÷ 2
tot = 48
Total even numbers from 55 to 150 = 48
Step 2) Calculate the sum of even numbers from 55 to 150
To calculate the sum of even numbers from 55 to 150, you enter the total even numbers (tot) from Step 1 and the first even number in the sequence into our formula. Here is the formula and the math:
sum = (tot ÷ 2) × (2 × first + (2 × (tot - 1))
sum = (48 ÷ 2) × (2 × 56 + (2 × (48 - 1))
sum = 24 × (112 + 94)
sum = 24 × 206
sum = 4944
Sum of even numbers from 55 to 150 = 4944
Step 3) Calculate the average of even numbers from 55 to 150
Almost done! Now we can calculate the average of even numbers from 55 to 150 by dividing the sum of even numbers from Step 2 by the total even numbers from Step 1. Here is the formula, the math, and the answer:
Average = sum ÷ tot
Average = 4944 ÷ 48
Average = 103
Average of even numbers from 55 to 150 = 103
