What is the average of even numbers from 4 to 60? Here we will show you how to calculate the average of even numbers from 4 to 60.
To find the average of the even numbers from 4 to 60, we first calculate how many even numbers there are from 4 to 60. Then, we calculate the sum of even numbers from 4 to 60. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 4 to 60, and the even numbers within that range are from 4 to 60. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 60.
Step 1) Calculate the total number of even numbers from 4 to 60
Here we calculate the total number of even numbers from 4 to 60 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 = (60 - 4 + 2) ÷ 2
tot = 58 ÷ 2
tot = 29
Total even numbers from 4 to 60 = 29
Step 2) Calculate the sum of even numbers from 4 to 60
To calculate the sum of even numbers from 4 to 60, 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 = (29 ÷ 2) × (2 × 4 + (2 × (29 - 1))
sum = 14.5 × (8 + 56)
sum = 14.5 × 64
sum = 928
Sum of even numbers from 4 to 60 = 928
Step 3) Calculate the average of even numbers from 4 to 60
Almost done! Now we can calculate the average of even numbers from 4 to 60 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 = 928 ÷ 29
Average = 32
Average of even numbers from 4 to 60 = 32
