What is the average of odd numbers from 170 to 175? Here we will show you how to calculate the average of odd numbers from 170 to 175.
To find the average of the odd numbers from 170 to 175, we first calculate how many odd numbers there are from 170 to 175. Then, we calculate the sum of odd numbers from 170 to 175. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 170 to 175, and the odd numbers within that range are from 171 to 175. Therefore, the first odd number in the sequence is 171, and the last odd number in the sequence is 175.
Step 1) Calculate the total number of odd numbers from 170 to 175
Here we calculate the total number of odd numbers from 170 to 175 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 = (175 - 171 + 2) ÷ 2
tot = 6 ÷ 2
tot = 3
Total odd numbers from 170 to 175 = 3
Step 2) Calculate the sum of odd numbers from 170 to 175
To calculate the sum of odd numbers from 170 to 175, 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 = (3 ÷ 2) × (2 × 171 + (2 × (3 - 1))
sum = 1.5 × (342 + 4)
sum = 1.5 × 346
sum = 519
Sum of odd numbers from 170 to 175 = 519
Step 3) Calculate the average of odd numbers from 170 to 175
Almost done! Now we can calculate the average of odd numbers from 170 to 175 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 = 519 ÷ 3
Average = 173
Average of odd numbers from 170 to 175 = 173
