What is the average of odd numbers from 101 to 108? Here we will show you how to calculate the average of odd numbers from 101 to 108.
To find the average of the odd numbers from 101 to 108, we first calculate how many odd numbers there are from 101 to 108. Then, we calculate the sum of odd numbers from 101 to 108. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 101 to 108, and the odd numbers within that range are from 101 to 107. Therefore, the first odd number in the sequence is 101, and the last odd number in the sequence is 107.
Step 1) Calculate the total number of odd numbers from 101 to 108
Here we calculate the total number of odd numbers from 101 to 108 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 = (107 - 101 + 2) ÷ 2
tot = 8 ÷ 2
tot = 4
Total odd numbers from 101 to 108 = 4
Step 2) Calculate the sum of odd numbers from 101 to 108
To calculate the sum of odd numbers from 101 to 108, 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 = (4 ÷ 2) × (2 × 101 + (2 × (4 - 1))
sum = 2 × (202 + 6)
sum = 2 × 208
sum = 416
Sum of odd numbers from 101 to 108 = 416
Step 3) Calculate the average of odd numbers from 101 to 108
Almost done! Now we can calculate the average of odd numbers from 101 to 108 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 = 416 ÷ 4
Average = 104
Average of odd numbers from 101 to 108 = 104
