What is the average of even numbers from 113 to 158? Here we will show you how to calculate the average of even numbers from 113 to 158.
To find the average of the even numbers from 113 to 158, we first calculate how many even numbers there are from 113 to 158. Then, we calculate the sum of even numbers from 113 to 158. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 113 to 158, and the even numbers within that range are from 114 to 158. Therefore, the first even number in the sequence is 114, and the last even number in the sequence is 158.
Step 1) Calculate the total number of even numbers from 113 to 158
Here we calculate the total number of even numbers from 113 to 158 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 = (158 - 114 + 2) ÷ 2
tot = 46 ÷ 2
tot = 23
Total even numbers from 113 to 158 = 23
Step 2) Calculate the sum of even numbers from 113 to 158
To calculate the sum of even numbers from 113 to 158, 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 = (23 ÷ 2) × (2 × 114 + (2 × (23 - 1))
sum = 11.5 × (228 + 44)
sum = 11.5 × 272
sum = 3128
Sum of even numbers from 113 to 158 = 3128
Step 3) Calculate the average of even numbers from 113 to 158
Almost done! Now we can calculate the average of even numbers from 113 to 158 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 = 3128 ÷ 23
Average = 136
Average of even numbers from 113 to 158 = 136
