What is the average of even numbers from 41 to 76? Here we will show you how to calculate the average of even numbers from 41 to 76.
To find the average of the even numbers from 41 to 76, we first calculate how many even numbers there are from 41 to 76. Then, we calculate the sum of even numbers from 41 to 76. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 41 to 76, and the even numbers within that range are from 42 to 76. Therefore, the first even number in the sequence is 42, and the last even number in the sequence is 76.
Step 1) Calculate the total number of even numbers from 41 to 76
Here we calculate the total number of even numbers from 41 to 76 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 = (76 - 42 + 2) ÷ 2
tot = 36 ÷ 2
tot = 18
Total even numbers from 41 to 76 = 18
Step 2) Calculate the sum of even numbers from 41 to 76
To calculate the sum of even numbers from 41 to 76, 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 = (18 ÷ 2) × (2 × 42 + (2 × (18 - 1))
sum = 9 × (84 + 34)
sum = 9 × 118
sum = 1062
Sum of even numbers from 41 to 76 = 1062
Step 3) Calculate the average of even numbers from 41 to 76
Almost done! Now we can calculate the average of even numbers from 41 to 76 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 = 1062 ÷ 18
Average = 59
Average of even numbers from 41 to 76 = 59
