What is the average of even numbers from 5 to 112? Here we will show you how to calculate the average of even numbers from 5 to 112.
To find the average of the even numbers from 5 to 112, we first calculate how many even numbers there are from 5 to 112. Then, we calculate the sum of even numbers from 5 to 112. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 5 to 112, and the even numbers within that range are from 6 to 112. Therefore, the first even number in the sequence is 6, and the last even number in the sequence is 112.
Step 1) Calculate the total number of even numbers from 5 to 112
Here we calculate the total number of even numbers from 5 to 112 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 = (112 - 6 + 2) ÷ 2
tot = 108 ÷ 2
tot = 54
Total even numbers from 5 to 112 = 54
Step 2) Calculate the sum of even numbers from 5 to 112
To calculate the sum of even numbers from 5 to 112, 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 = (54 ÷ 2) × (2 × 6 + (2 × (54 - 1))
sum = 27 × (12 + 106)
sum = 27 × 118
sum = 3186
Sum of even numbers from 5 to 112 = 3186
Step 3) Calculate the average of even numbers from 5 to 112
Almost done! Now we can calculate the average of even numbers from 5 to 112 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 = 3186 ÷ 54
Average = 59
Average of even numbers from 5 to 112 = 59
