What is the average of odd numbers from 2 to 98? Here we will show you how to calculate the average of odd numbers from 2 to 98.
To find the average of the odd numbers from 2 to 98, we first calculate how many odd numbers there are from 2 to 98. Then, we calculate the sum of odd numbers from 2 to 98. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 2 to 98, and the odd numbers within that range are from 3 to 97. Therefore, the first odd number in the sequence is 3, and the last odd number in the sequence is 97.
Step 1) Calculate the total number of odd numbers from 2 to 98
Here we calculate the total number of odd numbers from 2 to 98 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 = (97 - 3 + 2) ÷ 2
tot = 96 ÷ 2
tot = 48
Total odd numbers from 2 to 98 = 48
Step 2) Calculate the sum of odd numbers from 2 to 98
To calculate the sum of odd numbers from 2 to 98, 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 = (48 ÷ 2) × (2 × 3 + (2 × (48 - 1))
sum = 24 × (6 + 94)
sum = 24 × 100
sum = 2400
Sum of odd numbers from 2 to 98 = 2400
Step 3) Calculate the average of odd numbers from 2 to 98
Almost done! Now we can calculate the average of odd numbers from 2 to 98 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 = 2400 ÷ 48
Average = 50
Average of odd numbers from 2 to 98 = 50
