What is the average of odd numbers from 1 to 107? Here we will show you how to calculate the average of odd numbers from 1 to 107.
To find the average of the odd numbers from 1 to 107, we first calculate how many odd numbers there are from 1 to 107. Then, we calculate the sum of odd numbers from 1 to 107. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 107, and the odd numbers within that range are from 1 to 107. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 107.
Step 1) Calculate the total number of odd numbers from 1 to 107
Here we calculate the total number of odd numbers from 1 to 107 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 - 1 + 2) ÷ 2
tot = 108 ÷ 2
tot = 54
Total odd numbers from 1 to 107 = 54
Step 2) Calculate the sum of odd numbers from 1 to 107
To calculate the sum of odd numbers from 1 to 107, 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 = (54 ÷ 2) × (2 × 1 + (2 × (54 - 1))
sum = 27 × (2 + 106)
sum = 27 × 108
sum = 2916
Sum of odd numbers from 1 to 107 = 2916
Step 3) Calculate the average of odd numbers from 1 to 107
Almost done! Now we can calculate the average of odd numbers from 1 to 107 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 = 2916 ÷ 54
Average = 54
Average of odd numbers from 1 to 107 = 54
