What is the average of even numbers from 41 to 192? Here we will show you how to calculate the average of even numbers from 41 to 192.
To find the average of the even numbers from 41 to 192, we first calculate how many even numbers there are from 41 to 192. Then, we calculate the sum of even numbers from 41 to 192. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 41 to 192, and the even numbers within that range are from 42 to 192. Therefore, the first even number in the sequence is 42, and the last even number in the sequence is 192.
Step 1) Calculate the total number of even numbers from 41 to 192
Here we calculate the total number of even numbers from 41 to 192 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 = (192 - 42 + 2) ÷ 2
tot = 152 ÷ 2
tot = 76
Total even numbers from 41 to 192 = 76
Step 2) Calculate the sum of even numbers from 41 to 192
To calculate the sum of even numbers from 41 to 192, 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 = (76 ÷ 2) × (2 × 42 + (2 × (76 - 1))
sum = 38 × (84 + 150)
sum = 38 × 234
sum = 8892
Sum of even numbers from 41 to 192 = 8892
Step 3) Calculate the average of even numbers from 41 to 192
Almost done! Now we can calculate the average of even numbers from 41 to 192 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 = 8892 ÷ 76
Average = 117
Average of even numbers from 41 to 192 = 117
