What is the average of odd numbers from 4 to 24? Here we will show you how to calculate the average of odd numbers from 4 to 24.
To find the average of the odd numbers from 4 to 24, we first calculate how many odd numbers there are from 4 to 24. Then, we calculate the sum of odd numbers from 4 to 24. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 4 to 24, and the odd numbers within that range are from 5 to 23. Therefore, the first odd number in the sequence is 5, and the last odd number in the sequence is 23.
Step 1) Calculate the total number of odd numbers from 4 to 24
Here we calculate the total number of odd numbers from 4 to 24 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 = (23 - 5 + 2) ÷ 2
tot = 20 ÷ 2
tot = 10
Total odd numbers from 4 to 24 = 10
Step 2) Calculate the sum of odd numbers from 4 to 24
To calculate the sum of odd numbers from 4 to 24, 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 = (10 ÷ 2) × (2 × 5 + (2 × (10 - 1))
sum = 5 × (10 + 18)
sum = 5 × 28
sum = 140
Sum of odd numbers from 4 to 24 = 140
Step 3) Calculate the average of odd numbers from 4 to 24
Almost done! Now we can calculate the average of odd numbers from 4 to 24 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 = 140 ÷ 10
Average = 14
Average of odd numbers from 4 to 24 = 14
