What is the average of odd numbers from 2 to 47? Here we will show you how to calculate the average of odd numbers from 2 to 47.
To find the average of the odd numbers from 2 to 47, we first calculate how many odd numbers there are from 2 to 47. Then, we calculate the sum of odd numbers from 2 to 47. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 2 to 47, and the odd numbers within that range are from 3 to 47. Therefore, the first odd number in the sequence is 3, and the last odd number in the sequence is 47.
Step 1) Calculate the total number of odd numbers from 2 to 47
Here we calculate the total number of odd numbers from 2 to 47 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 = (47 - 3 + 2) ÷ 2
tot = 46 ÷ 2
tot = 23
Total odd numbers from 2 to 47 = 23
Step 2) Calculate the sum of odd numbers from 2 to 47
To calculate the sum of odd numbers from 2 to 47, 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 = (23 ÷ 2) × (2 × 3 + (2 × (23 - 1))
sum = 11.5 × (6 + 44)
sum = 11.5 × 50
sum = 575
Sum of odd numbers from 2 to 47 = 575
Step 3) Calculate the average of odd numbers from 2 to 47
Almost done! Now we can calculate the average of odd numbers from 2 to 47 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 = 575 ÷ 23
Average = 25
Average of odd numbers from 2 to 47 = 25
