What is the average of even numbers from 13 to 59? Here we will show you how to calculate the average of even numbers from 13 to 59.
To find the average of the even numbers from 13 to 59, we first calculate how many even numbers there are from 13 to 59. Then, we calculate the sum of even numbers from 13 to 59. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 13 to 59, and the even numbers within that range are from 14 to 58. Therefore, the first even number in the sequence is 14, and the last even number in the sequence is 58.
Step 1) Calculate the total number of even numbers from 13 to 59
Here we calculate the total number of even numbers from 13 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 - 14 + 2) ÷ 2
tot = 46 ÷ 2
tot = 23
Total even numbers from 13 to 59 = 23
Step 2) Calculate the sum of even numbers from 13 to 59
To calculate the sum of even numbers from 13 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 = (23 ÷ 2) × (2 × 14 + (2 × (23 - 1))
sum = 11.5 × (28 + 44)
sum = 11.5 × 72
sum = 828
Sum of even numbers from 13 to 59 = 828
Step 3) Calculate the average of even numbers from 13 to 59
Almost done! Now we can calculate the average of even numbers from 13 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 = 828 ÷ 23
Average = 36
Average of even numbers from 13 to 59 = 36
