What is the average of even numbers from 1 to 107? Here we will show you how to calculate the average of even numbers from 1 to 107.
To find the average of the even numbers from 1 to 107, we first calculate how many even numbers there are from 1 to 107. Then, we calculate the sum of even numbers from 1 to 107. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 107, and the even numbers within that range are from 2 to 106. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 106.
Step 1) Calculate the total number of even numbers from 1 to 107
Here we calculate the total number of even numbers from 1 to 107 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 = (106 - 2 + 2) ÷ 2
tot = 106 ÷ 2
tot = 53
Total even numbers from 1 to 107 = 53
Step 2) Calculate the sum of even numbers from 1 to 107
To calculate the sum of even numbers from 1 to 107, 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 = (53 ÷ 2) × (2 × 2 + (2 × (53 - 1))
sum = 26.5 × (4 + 104)
sum = 26.5 × 108
sum = 2862
Sum of even numbers from 1 to 107 = 2862
Step 3) Calculate the average of even numbers from 1 to 107
Almost done! Now we can calculate the average of even numbers from 1 to 107 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 = 2862 ÷ 53
Average = 54
Average of even numbers from 1 to 107 = 54
