What is the average of even numbers from 4 to 46? Here we will show you how to calculate the average of even numbers from 4 to 46.
To find the average of the even numbers from 4 to 46, we first calculate how many even numbers there are from 4 to 46. Then, we calculate the sum of even numbers from 4 to 46. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 4 to 46, and the even numbers within that range are from 4 to 46. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 46.
Step 1) Calculate the total number of even numbers from 4 to 46
Here we calculate the total number of even numbers from 4 to 46 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 - 4 + 2) ÷ 2
tot = 44 ÷ 2
tot = 22
Total even numbers from 4 to 46 = 22
Step 2) Calculate the sum of even numbers from 4 to 46
To calculate the sum of even numbers from 4 to 46, 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 × 4 + (2 × (22 - 1))
sum = 11 × (8 + 42)
sum = 11 × 50
sum = 550
Sum of even numbers from 4 to 46 = 550
Step 3) Calculate the average of even numbers from 4 to 46
Almost done! Now we can calculate the average of even numbers from 4 to 46 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 = 550 ÷ 22
Average = 25
Average of even numbers from 4 to 46 = 25
