What is the average of odd numbers from 4 to 22? Here we will show you how to calculate the average of odd numbers from 4 to 22.
To find the average of the odd numbers from 4 to 22, we first calculate how many odd numbers there are from 4 to 22. Then, we calculate the sum of odd numbers from 4 to 22. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 4 to 22, and the odd numbers within that range are from 5 to 21. Therefore, the first odd number in the sequence is 5, and the last odd number in the sequence is 21.
Step 1) Calculate the total number of odd numbers from 4 to 22
Here we calculate the total number of odd numbers from 4 to 22 by entering the first and last odd number in the sequence into our formula. Here is the formula and the math:
tot = (last - first + 2) ÷ 2
tot = (21 - 5 + 2) ÷ 2
tot = 18 ÷ 2
tot = 9
Total odd numbers from 4 to 22 = 9
Step 2) Calculate the sum of odd numbers from 4 to 22
To calculate the sum of odd numbers from 4 to 22, you enter the total odd numbers (tot) from Step 1 and the first odd number in the sequence into our formula. Here is the formula and the math:
sum = (tot ÷ 2) × (2 × first + (2 × (tot - 1))
sum = (9 ÷ 2) × (2 × 5 + (2 × (9 - 1))
sum = 4.5 × (10 + 16)
sum = 4.5 × 26
sum = 117
Sum of odd numbers from 4 to 22 = 117
Step 3) Calculate the average of odd numbers from 4 to 22
Almost done! Now we can calculate the average of odd numbers from 4 to 22 by dividing the sum of odd numbers from Step 2 by the total odd numbers from Step 1. Here is the formula, the math, and the answer:
Average = sum ÷ tot
Average = 117 ÷ 9
Average = 13
Average of odd numbers from 4 to 22 = 13
