What is the average of even numbers from 13 to 16? Here we will show you how to calculate the average of even numbers from 13 to 16.
To find the average of the even numbers from 13 to 16, we first calculate how many even numbers there are from 13 to 16. Then, we calculate the sum of even numbers from 13 to 16. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 13 to 16, and the even numbers within that range are from 14 to 16. Therefore, the first even number in the sequence is 14, and the last even number in the sequence is 16.
Step 1) Calculate the total number of even numbers from 13 to 16
Here we calculate the total number of even numbers from 13 to 16 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 = (16 - 14 + 2) ÷ 2
tot = 4 ÷ 2
tot = 2
Total even numbers from 13 to 16 = 2
Step 2) Calculate the sum of even numbers from 13 to 16
To calculate the sum of even numbers from 13 to 16, 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 = (2 ÷ 2) × (2 × 14 + (2 × (2 - 1))
sum = 1 × (28 + 2)
sum = 1 × 30
sum = 30
Sum of even numbers from 13 to 16 = 30
Step 3) Calculate the average of even numbers from 13 to 16
Almost done! Now we can calculate the average of even numbers from 13 to 16 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 = 30 ÷ 2
Average = 15
Average of even numbers from 13 to 16 = 15
