What is the average of odd numbers from 6 to 154? Here we will show you how to calculate the average of odd numbers from 6 to 154.
To find the average of the odd numbers from 6 to 154, we first calculate how many odd numbers there are from 6 to 154. Then, we calculate the sum of odd numbers from 6 to 154. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 6 to 154, and the odd numbers within that range are from 7 to 153. Therefore, the first odd number in the sequence is 7, and the last odd number in the sequence is 153.
Step 1) Calculate the total number of odd numbers from 6 to 154
Here we calculate the total number of odd numbers from 6 to 154 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 = (153 - 7 + 2) ÷ 2
tot = 148 ÷ 2
tot = 74
Total odd numbers from 6 to 154 = 74
Step 2) Calculate the sum of odd numbers from 6 to 154
To calculate the sum of odd numbers from 6 to 154, 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 = (74 ÷ 2) × (2 × 7 + (2 × (74 - 1))
sum = 37 × (14 + 146)
sum = 37 × 160
sum = 5920
Sum of odd numbers from 6 to 154 = 5920
Step 3) Calculate the average of odd numbers from 6 to 154
Almost done! Now we can calculate the average of odd numbers from 6 to 154 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 = 5920 ÷ 74
Average = 80
Average of odd numbers from 6 to 154 = 80
