What is the average of even numbers from 4 to 59? Here we will show you how to calculate the average of even numbers from 4 to 59.
To find the average of the even numbers from 4 to 59, we first calculate how many even numbers there are from 4 to 59. Then, we calculate the sum of even numbers from 4 to 59. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 4 to 59, and the even numbers within that range are from 4 to 58. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 58.
Step 1) Calculate the total number of even numbers from 4 to 59
Here we calculate the total number of even numbers from 4 to 59 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 = (58 - 4 + 2) ÷ 2
tot = 56 ÷ 2
tot = 28
Total even numbers from 4 to 59 = 28
Step 2) Calculate the sum of even numbers from 4 to 59
To calculate the sum of even numbers from 4 to 59, 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 = (28 ÷ 2) × (2 × 4 + (2 × (28 - 1))
sum = 14 × (8 + 54)
sum = 14 × 62
sum = 868
Sum of even numbers from 4 to 59 = 868
Step 3) Calculate the average of even numbers from 4 to 59
Almost done! Now we can calculate the average of even numbers from 4 to 59 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 = 868 ÷ 28
Average = 31
Average of even numbers from 4 to 59 = 31
