What is the average of even numbers from 13 to 188? Here we will show you how to calculate the average of even numbers from 13 to 188.
To find the average of the even numbers from 13 to 188, we first calculate how many even numbers there are from 13 to 188. Then, we calculate the sum of even numbers from 13 to 188. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 13 to 188, and the even numbers within that range are from 14 to 188. Therefore, the first even number in the sequence is 14, and the last even number in the sequence is 188.
Step 1) Calculate the total number of even numbers from 13 to 188
Here we calculate the total number of even numbers from 13 to 188 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 = (188 - 14 + 2) ÷ 2
tot = 176 ÷ 2
tot = 88
Total even numbers from 13 to 188 = 88
Step 2) Calculate the sum of even numbers from 13 to 188
To calculate the sum of even numbers from 13 to 188, 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 = (88 ÷ 2) × (2 × 14 + (2 × (88 - 1))
sum = 44 × (28 + 174)
sum = 44 × 202
sum = 8888
Sum of even numbers from 13 to 188 = 8888
Step 3) Calculate the average of even numbers from 13 to 188
Almost done! Now we can calculate the average of even numbers from 13 to 188 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 = 8888 ÷ 88
Average = 101
Average of even numbers from 13 to 188 = 101
