What is the average of even numbers from 157 to 175? Here we will show you how to calculate the average of even numbers from 157 to 175.
To find the average of the even numbers from 157 to 175, we first calculate how many even numbers there are from 157 to 175. Then, we calculate the sum of even numbers from 157 to 175. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 157 to 175, and the even numbers within that range are from 158 to 174. Therefore, the first even number in the sequence is 158, and the last even number in the sequence is 174.
Step 1) Calculate the total number of even numbers from 157 to 175
Here we calculate the total number of even numbers from 157 to 175 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 = (174 - 158 + 2) ÷ 2
tot = 18 ÷ 2
tot = 9
Total even numbers from 157 to 175 = 9
Step 2) Calculate the sum of even numbers from 157 to 175
To calculate the sum of even numbers from 157 to 175, 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 = (9 ÷ 2) × (2 × 158 + (2 × (9 - 1))
sum = 4.5 × (316 + 16)
sum = 4.5 × 332
sum = 1494
Sum of even numbers from 157 to 175 = 1494
Step 3) Calculate the average of even numbers from 157 to 175
Almost done! Now we can calculate the average of even numbers from 157 to 175 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 = 1494 ÷ 9
Average = 166
Average of even numbers from 157 to 175 = 166
