What is the average of odd numbers from 47 to 195? Here we will show you how to calculate the average of odd numbers from 47 to 195.
To find the average of the odd numbers from 47 to 195, we first calculate how many odd numbers there are from 47 to 195. Then, we calculate the sum of odd numbers from 47 to 195. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 47 to 195, and the odd numbers within that range are from 47 to 195. Therefore, the first odd number in the sequence is 47, and the last odd number in the sequence is 195.
Step 1) Calculate the total number of odd numbers from 47 to 195
Here we calculate the total number of odd numbers from 47 to 195 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 = (195 - 47 + 2) ÷ 2
tot = 150 ÷ 2
tot = 75
Total odd numbers from 47 to 195 = 75
Step 2) Calculate the sum of odd numbers from 47 to 195
To calculate the sum of odd numbers from 47 to 195, 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 = (75 ÷ 2) × (2 × 47 + (2 × (75 - 1))
sum = 37.5 × (94 + 148)
sum = 37.5 × 242
sum = 9075
Sum of odd numbers from 47 to 195 = 9075
Step 3) Calculate the average of odd numbers from 47 to 195
Almost done! Now we can calculate the average of odd numbers from 47 to 195 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 = 9075 ÷ 75
Average = 121
Average of odd numbers from 47 to 195 = 121
