What is the average of even numbers from 5 to 47? Here we will show you how to calculate the average of even numbers from 5 to 47.
To find the average of the even numbers from 5 to 47, we first calculate how many even numbers there are from 5 to 47. Then, we calculate the sum of even numbers from 5 to 47. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 5 to 47, and the even numbers within that range are from 6 to 46. Therefore, the first even number in the sequence is 6, and the last even number in the sequence is 46.
Step 1) Calculate the total number of even numbers from 5 to 47
Here we calculate the total number of even numbers from 5 to 47 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 = (46 - 6 + 2) ÷ 2
tot = 42 ÷ 2
tot = 21
Total even numbers from 5 to 47 = 21
Step 2) Calculate the sum of even numbers from 5 to 47
To calculate the sum of even numbers from 5 to 47, 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 = (21 ÷ 2) × (2 × 6 + (2 × (21 - 1))
sum = 10.5 × (12 + 40)
sum = 10.5 × 52
sum = 546
Sum of even numbers from 5 to 47 = 546
Step 3) Calculate the average of even numbers from 5 to 47
Almost done! Now we can calculate the average of even numbers from 5 to 47 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 = 546 ÷ 21
Average = 26
Average of even numbers from 5 to 47 = 26
