What is the average of odd numbers from 33 to 132? Here we will show you how to calculate the average of odd numbers from 33 to 132.
To find the average of the odd numbers from 33 to 132, we first calculate how many odd numbers there are from 33 to 132. Then, we calculate the sum of odd numbers from 33 to 132. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 33 to 132, and the odd numbers within that range are from 33 to 131. Therefore, the first odd number in the sequence is 33, and the last odd number in the sequence is 131.
Step 1) Calculate the total number of odd numbers from 33 to 132
Here we calculate the total number of odd numbers from 33 to 132 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 = (131 - 33 + 2) ÷ 2
tot = 100 ÷ 2
tot = 50
Total odd numbers from 33 to 132 = 50
Step 2) Calculate the sum of odd numbers from 33 to 132
To calculate the sum of odd numbers from 33 to 132, 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 = (50 ÷ 2) × (2 × 33 + (2 × (50 - 1))
sum = 25 × (66 + 98)
sum = 25 × 164
sum = 4100
Sum of odd numbers from 33 to 132 = 4100
Step 3) Calculate the average of odd numbers from 33 to 132
Almost done! Now we can calculate the average of odd numbers from 33 to 132 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 = 4100 ÷ 50
Average = 82
Average of odd numbers from 33 to 132 = 82
