What is the average of odd numbers from 138 to 194? Here we will show you how to calculate the average of odd numbers from 138 to 194.
To find the average of the odd numbers from 138 to 194, we first calculate how many odd numbers there are from 138 to 194. Then, we calculate the sum of odd numbers from 138 to 194. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 138 to 194, and the odd numbers within that range are from 139 to 193. Therefore, the first odd number in the sequence is 139, and the last odd number in the sequence is 193.
Step 1) Calculate the total number of odd numbers from 138 to 194
Here we calculate the total number of odd numbers from 138 to 194 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 = (193 - 139 + 2) ÷ 2
tot = 56 ÷ 2
tot = 28
Total odd numbers from 138 to 194 = 28
Step 2) Calculate the sum of odd numbers from 138 to 194
To calculate the sum of odd numbers from 138 to 194, 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 = (28 ÷ 2) × (2 × 139 + (2 × (28 - 1))
sum = 14 × (278 + 54)
sum = 14 × 332
sum = 4648
Sum of odd numbers from 138 to 194 = 4648
Step 3) Calculate the average of odd numbers from 138 to 194
Almost done! Now we can calculate the average of odd numbers from 138 to 194 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 = 4648 ÷ 28
Average = 166
Average of odd numbers from 138 to 194 = 166
