What is the average of odd numbers from 94 to 156? Here we will show you how to calculate the average of odd numbers from 94 to 156.
To find the average of the odd numbers from 94 to 156, we first calculate how many odd numbers there are from 94 to 156. Then, we calculate the sum of odd numbers from 94 to 156. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 94 to 156, and the odd numbers within that range are from 95 to 155. Therefore, the first odd number in the sequence is 95, and the last odd number in the sequence is 155.
Step 1) Calculate the total number of odd numbers from 94 to 156
Here we calculate the total number of odd numbers from 94 to 156 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 = (155 - 95 + 2) ÷ 2
tot = 62 ÷ 2
tot = 31
Total odd numbers from 94 to 156 = 31
Step 2) Calculate the sum of odd numbers from 94 to 156
To calculate the sum of odd numbers from 94 to 156, 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 = (31 ÷ 2) × (2 × 95 + (2 × (31 - 1))
sum = 15.5 × (190 + 60)
sum = 15.5 × 250
sum = 3875
Sum of odd numbers from 94 to 156 = 3875
Step 3) Calculate the average of odd numbers from 94 to 156
Almost done! Now we can calculate the average of odd numbers from 94 to 156 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 = 3875 ÷ 31
Average = 125
Average of odd numbers from 94 to 156 = 125
