What is the average of odd numbers from 6 to 83? Here we will show you how to calculate the average of odd numbers from 6 to 83.
To find the average of the odd numbers from 6 to 83, we first calculate how many odd numbers there are from 6 to 83. Then, we calculate the sum of odd numbers from 6 to 83. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 6 to 83, and the odd numbers within that range are from 7 to 83. Therefore, the first odd number in the sequence is 7, and the last odd number in the sequence is 83.
Step 1) Calculate the total number of odd numbers from 6 to 83
Here we calculate the total number of odd numbers from 6 to 83 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 = (83 - 7 + 2) ÷ 2
tot = 78 ÷ 2
tot = 39
Total odd numbers from 6 to 83 = 39
Step 2) Calculate the sum of odd numbers from 6 to 83
To calculate the sum of odd numbers from 6 to 83, 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 = (39 ÷ 2) × (2 × 7 + (2 × (39 - 1))
sum = 19.5 × (14 + 76)
sum = 19.5 × 90
sum = 1755
Sum of odd numbers from 6 to 83 = 1755
Step 3) Calculate the average of odd numbers from 6 to 83
Almost done! Now we can calculate the average of odd numbers from 6 to 83 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 = 1755 ÷ 39
Average = 45
Average of odd numbers from 6 to 83 = 45
