What is the average of even numbers from 1 to 66? Here we will show you how to calculate the average of even numbers from 1 to 66.
To find the average of the even numbers from 1 to 66, we first calculate how many even numbers there are from 1 to 66. Then, we calculate the sum of even numbers from 1 to 66. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 66, and the even numbers within that range are from 2 to 66. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 66.
Step 1) Calculate the total number of even numbers from 1 to 66
Here we calculate the total number of even numbers from 1 to 66 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 = (66 - 2 + 2) ÷ 2
tot = 66 ÷ 2
tot = 33
Total even numbers from 1 to 66 = 33
Step 2) Calculate the sum of even numbers from 1 to 66
To calculate the sum of even numbers from 1 to 66, 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 = (33 ÷ 2) × (2 × 2 + (2 × (33 - 1))
sum = 16.5 × (4 + 64)
sum = 16.5 × 68
sum = 1122
Sum of even numbers from 1 to 66 = 1122
Step 3) Calculate the average of even numbers from 1 to 66
Almost done! Now we can calculate the average of even numbers from 1 to 66 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 = 1122 ÷ 33
Average = 34
Average of even numbers from 1 to 66 = 34
