What is the average of even numbers from 165 to 177? Here we will show you how to calculate the average of even numbers from 165 to 177.
To find the average of the even numbers from 165 to 177, we first calculate how many even numbers there are from 165 to 177. Then, we calculate the sum of even numbers from 165 to 177. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 165 to 177, and the even numbers within that range are from 166 to 176. Therefore, the first even number in the sequence is 166, and the last even number in the sequence is 176.
Step 1) Calculate the total number of even numbers from 165 to 177
Here we calculate the total number of even numbers from 165 to 177 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 = (176 - 166 + 2) ÷ 2
tot = 12 ÷ 2
tot = 6
Total even numbers from 165 to 177 = 6
Step 2) Calculate the sum of even numbers from 165 to 177
To calculate the sum of even numbers from 165 to 177, 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 = (6 ÷ 2) × (2 × 166 + (2 × (6 - 1))
sum = 3 × (332 + 10)
sum = 3 × 342
sum = 1026
Sum of even numbers from 165 to 177 = 1026
Step 3) Calculate the average of even numbers from 165 to 177
Almost done! Now we can calculate the average of even numbers from 165 to 177 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 = 1026 ÷ 6
Average = 171
Average of even numbers from 165 to 177 = 171
