What is the average of odd numbers from 137 to 174? Here we will show you how to calculate the average of odd numbers from 137 to 174.
To find the average of the odd numbers from 137 to 174, we first calculate how many odd numbers there are from 137 to 174. Then, we calculate the sum of odd numbers from 137 to 174. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 137 to 174, and the odd numbers within that range are from 137 to 173. Therefore, the first odd number in the sequence is 137, and the last odd number in the sequence is 173.
Step 1) Calculate the total number of odd numbers from 137 to 174
Here we calculate the total number of odd numbers from 137 to 174 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 = (173 - 137 + 2) ÷ 2
tot = 38 ÷ 2
tot = 19
Total odd numbers from 137 to 174 = 19
Step 2) Calculate the sum of odd numbers from 137 to 174
To calculate the sum of odd numbers from 137 to 174, 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 = (19 ÷ 2) × (2 × 137 + (2 × (19 - 1))
sum = 9.5 × (274 + 36)
sum = 9.5 × 310
sum = 2945
Sum of odd numbers from 137 to 174 = 2945
Step 3) Calculate the average of odd numbers from 137 to 174
Almost done! Now we can calculate the average of odd numbers from 137 to 174 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 = 2945 ÷ 19
Average = 155
Average of odd numbers from 137 to 174 = 155
