What is the average of even numbers from 4 to 133? Here we will show you how to calculate the average of even numbers from 4 to 133.
To find the average of the even numbers from 4 to 133, we first calculate how many even numbers there are from 4 to 133. Then, we calculate the sum of even numbers from 4 to 133. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 4 to 133, and the even numbers within that range are from 4 to 132. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 132.
Step 1) Calculate the total number of even numbers from 4 to 133
Here we calculate the total number of even numbers from 4 to 133 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 = (132 - 4 + 2) ÷ 2
tot = 130 ÷ 2
tot = 65
Total even numbers from 4 to 133 = 65
Step 2) Calculate the sum of even numbers from 4 to 133
To calculate the sum of even numbers from 4 to 133, 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 = (65 ÷ 2) × (2 × 4 + (2 × (65 - 1))
sum = 32.5 × (8 + 128)
sum = 32.5 × 136
sum = 4420
Sum of even numbers from 4 to 133 = 4420
Step 3) Calculate the average of even numbers from 4 to 133
Almost done! Now we can calculate the average of even numbers from 4 to 133 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 = 4420 ÷ 65
Average = 68
Average of even numbers from 4 to 133 = 68
