What is the average of even numbers from 144 to 186? Here we will show you how to calculate the average of even numbers from 144 to 186.
To find the average of the even numbers from 144 to 186, we first calculate how many even numbers there are from 144 to 186. Then, we calculate the sum of even numbers from 144 to 186. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 144 to 186, and the even numbers within that range are from 144 to 186. Therefore, the first even number in the sequence is 144, and the last even number in the sequence is 186.
Step 1) Calculate the total number of even numbers from 144 to 186
Here we calculate the total number of even numbers from 144 to 186 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 = (186 - 144 + 2) ÷ 2
tot = 44 ÷ 2
tot = 22
Total even numbers from 144 to 186 = 22
Step 2) Calculate the sum of even numbers from 144 to 186
To calculate the sum of even numbers from 144 to 186, 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 = (22 ÷ 2) × (2 × 144 + (2 × (22 - 1))
sum = 11 × (288 + 42)
sum = 11 × 330
sum = 3630
Sum of even numbers from 144 to 186 = 3630
Step 3) Calculate the average of even numbers from 144 to 186
Almost done! Now we can calculate the average of even numbers from 144 to 186 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 = 3630 ÷ 22
Average = 165
Average of even numbers from 144 to 186 = 165
