What is the average of odd numbers from 1 to 7420? Here we will show you how to calculate the average of odd numbers from 1 to 7420.
To find the average of the odd numbers from 1 to 7420, we first calculate how many odd numbers there are from 1 to 7420. Then, we calculate the sum of odd numbers from 1 to 7420. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 7420, and the odd numbers within that range are from 1 to 7419. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 7419.
Step 1) Calculate the total number of odd numbers from 1 to 7420
Here we calculate the total number of odd numbers from 1 to 7420 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 = (7419 - 1 + 2) ÷ 2
tot = 7420 ÷ 2
tot = 3710
Total odd numbers from 1 to 7420 = 3710
Step 2) Calculate the sum of odd numbers from 1 to 7420
To calculate the sum of odd numbers from 1 to 7420, 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 = (3710 ÷ 2) × (2 × 1 + (2 × (3710 - 1))
sum = 1855 × (2 + 7418)
sum = 1855 × 7420
sum = 13764100
Sum of odd numbers from 1 to 7420 = 13764100
Step 3) Calculate the average of odd numbers from 1 to 7420
Almost done! Now we can calculate the average of odd numbers from 1 to 7420 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 = 13764100 ÷ 3710
Average = 3710
Average of odd numbers from 1 to 7420 = 3710
