What is the average of odd numbers from 4 to 32? Here we will show you how to calculate the average of odd numbers from 4 to 32.
To find the average of the odd numbers from 4 to 32, we first calculate how many odd numbers there are from 4 to 32. Then, we calculate the sum of odd numbers from 4 to 32. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 4 to 32, and the odd numbers within that range are from 5 to 31. Therefore, the first odd number in the sequence is 5, and the last odd number in the sequence is 31.
Step 1) Calculate the total number of odd numbers from 4 to 32
Here we calculate the total number of odd numbers from 4 to 32 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 = (31 - 5 + 2) ÷ 2
tot = 28 ÷ 2
tot = 14
Total odd numbers from 4 to 32 = 14
Step 2) Calculate the sum of odd numbers from 4 to 32
To calculate the sum of odd numbers from 4 to 32, 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 = (14 ÷ 2) × (2 × 5 + (2 × (14 - 1))
sum = 7 × (10 + 26)
sum = 7 × 36
sum = 252
Sum of odd numbers from 4 to 32 = 252
Step 3) Calculate the average of odd numbers from 4 to 32
Almost done! Now we can calculate the average of odd numbers from 4 to 32 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 = 252 ÷ 14
Average = 18
Average of odd numbers from 4 to 32 = 18
