What is the average of even numbers from 26 to 45? Here we will show you how to calculate the average of even numbers from 26 to 45.
To find the average of the even numbers from 26 to 45, we first calculate how many even numbers there are from 26 to 45. Then, we calculate the sum of even numbers from 26 to 45. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 26 to 45, and the even numbers within that range are from 26 to 44. Therefore, the first even number in the sequence is 26, and the last even number in the sequence is 44.
Step 1) Calculate the total number of even numbers from 26 to 45
Here we calculate the total number of even numbers from 26 to 45 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 = (44 - 26 + 2) ÷ 2
tot = 20 ÷ 2
tot = 10
Total even numbers from 26 to 45 = 10
Step 2) Calculate the sum of even numbers from 26 to 45
To calculate the sum of even numbers from 26 to 45, 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 = (10 ÷ 2) × (2 × 26 + (2 × (10 - 1))
sum = 5 × (52 + 18)
sum = 5 × 70
sum = 350
Sum of even numbers from 26 to 45 = 350
Step 3) Calculate the average of even numbers from 26 to 45
Almost done! Now we can calculate the average of even numbers from 26 to 45 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 = 350 ÷ 10
Average = 35
Average of even numbers from 26 to 45 = 35
