What is the average of odd numbers from 125 to 200? Here we will show you how to calculate the average of odd numbers from 125 to 200.
To find the average of the odd numbers from 125 to 200, we first calculate how many odd numbers there are from 125 to 200. Then, we calculate the sum of odd numbers from 125 to 200. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 125 to 200, and the odd numbers within that range are from 125 to 199. Therefore, the first odd number in the sequence is 125, and the last odd number in the sequence is 199.
Step 1) Calculate the total number of odd numbers from 125 to 200
Here we calculate the total number of odd numbers from 125 to 200 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 = (199 - 125 + 2) ÷ 2
tot = 76 ÷ 2
tot = 38
Total odd numbers from 125 to 200 = 38
Step 2) Calculate the sum of odd numbers from 125 to 200
To calculate the sum of odd numbers from 125 to 200, 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 = (38 ÷ 2) × (2 × 125 + (2 × (38 - 1))
sum = 19 × (250 + 74)
sum = 19 × 324
sum = 6156
Sum of odd numbers from 125 to 200 = 6156
Step 3) Calculate the average of odd numbers from 125 to 200
Almost done! Now we can calculate the average of odd numbers from 125 to 200 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 = 6156 ÷ 38
Average = 162
Average of odd numbers from 125 to 200 = 162
