What is the average of odd numbers from 1 to 7149? Here we will show you how to calculate the average of odd numbers from 1 to 7149.
To find the average of the odd numbers from 1 to 7149, we first calculate how many odd numbers there are from 1 to 7149. Then, we calculate the sum of odd numbers from 1 to 7149. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 7149, and the odd numbers within that range are from 1 to 7149. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 7149.
Step 1) Calculate the total number of odd numbers from 1 to 7149
Here we calculate the total number of odd numbers from 1 to 7149 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 = (7149 - 1 + 2) ÷ 2
tot = 7150 ÷ 2
tot = 3575
Total odd numbers from 1 to 7149 = 3575
Step 2) Calculate the sum of odd numbers from 1 to 7149
To calculate the sum of odd numbers from 1 to 7149, 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 = (3575 ÷ 2) × (2 × 1 + (2 × (3575 - 1))
sum = 1787.5 × (2 + 7148)
sum = 1787.5 × 7150
sum = 12780625
Sum of odd numbers from 1 to 7149 = 12780625
Step 3) Calculate the average of odd numbers from 1 to 7149
Almost done! Now we can calculate the average of odd numbers from 1 to 7149 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 = 12780625 ÷ 3575
Average = 3575
Average of odd numbers from 1 to 7149 = 3575
