What is the average of odd numbers from 64 to 162? Here we will show you how to calculate the average of odd numbers from 64 to 162.
To find the average of the odd numbers from 64 to 162, we first calculate how many odd numbers there are from 64 to 162. Then, we calculate the sum of odd numbers from 64 to 162. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 64 to 162, and the odd numbers within that range are from 65 to 161. Therefore, the first odd number in the sequence is 65, and the last odd number in the sequence is 161.
Step 1) Calculate the total number of odd numbers from 64 to 162
Here we calculate the total number of odd numbers from 64 to 162 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 = (161 - 65 + 2) ÷ 2
tot = 98 ÷ 2
tot = 49
Total odd numbers from 64 to 162 = 49
Step 2) Calculate the sum of odd numbers from 64 to 162
To calculate the sum of odd numbers from 64 to 162, 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 = (49 ÷ 2) × (2 × 65 + (2 × (49 - 1))
sum = 24.5 × (130 + 96)
sum = 24.5 × 226
sum = 5537
Sum of odd numbers from 64 to 162 = 5537
Step 3) Calculate the average of odd numbers from 64 to 162
Almost done! Now we can calculate the average of odd numbers from 64 to 162 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 = 5537 ÷ 49
Average = 113
Average of odd numbers from 64 to 162 = 113
