What is the average of odd numbers from 106 to 166? Here we will show you how to calculate the average of odd numbers from 106 to 166.
To find the average of the odd numbers from 106 to 166, we first calculate how many odd numbers there are from 106 to 166. Then, we calculate the sum of odd numbers from 106 to 166. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 106 to 166, and the odd numbers within that range are from 107 to 165. Therefore, the first odd number in the sequence is 107, and the last odd number in the sequence is 165.
Step 1) Calculate the total number of odd numbers from 106 to 166
Here we calculate the total number of odd numbers from 106 to 166 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 = (165 - 107 + 2) ÷ 2
tot = 60 ÷ 2
tot = 30
Total odd numbers from 106 to 166 = 30
Step 2) Calculate the sum of odd numbers from 106 to 166
To calculate the sum of odd numbers from 106 to 166, 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 = (30 ÷ 2) × (2 × 107 + (2 × (30 - 1))
sum = 15 × (214 + 58)
sum = 15 × 272
sum = 4080
Sum of odd numbers from 106 to 166 = 4080
Step 3) Calculate the average of odd numbers from 106 to 166
Almost done! Now we can calculate the average of odd numbers from 106 to 166 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 = 4080 ÷ 30
Average = 136
Average of odd numbers from 106 to 166 = 136
