What is the average of odd numbers from 2 to 104? Here we will show you how to calculate the average of odd numbers from 2 to 104.
To find the average of the odd numbers from 2 to 104, we first calculate how many odd numbers there are from 2 to 104. Then, we calculate the sum of odd numbers from 2 to 104. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 2 to 104, and the odd numbers within that range are from 3 to 103. Therefore, the first odd number in the sequence is 3, and the last odd number in the sequence is 103.
Step 1) Calculate the total number of odd numbers from 2 to 104
Here we calculate the total number of odd numbers from 2 to 104 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 = (103 - 3 + 2) ÷ 2
tot = 102 ÷ 2
tot = 51
Total odd numbers from 2 to 104 = 51
Step 2) Calculate the sum of odd numbers from 2 to 104
To calculate the sum of odd numbers from 2 to 104, 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 = (51 ÷ 2) × (2 × 3 + (2 × (51 - 1))
sum = 25.5 × (6 + 100)
sum = 25.5 × 106
sum = 2703
Sum of odd numbers from 2 to 104 = 2703
Step 3) Calculate the average of odd numbers from 2 to 104
Almost done! Now we can calculate the average of odd numbers from 2 to 104 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 = 2703 ÷ 51
Average = 53
Average of odd numbers from 2 to 104 = 53
