What is the average of odd numbers from 1 to 7820? Here we will show you how to calculate the average of odd numbers from 1 to 7820.
To find the average of the odd numbers from 1 to 7820, we first calculate how many odd numbers there are from 1 to 7820. Then, we calculate the sum of odd numbers from 1 to 7820. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 7820, and the odd numbers within that range are from 1 to 7819. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 7819.
Step 1) Calculate the total number of odd numbers from 1 to 7820
Here we calculate the total number of odd numbers from 1 to 7820 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 = (7819 - 1 + 2) ÷ 2
tot = 7820 ÷ 2
tot = 3910
Total odd numbers from 1 to 7820 = 3910
Step 2) Calculate the sum of odd numbers from 1 to 7820
To calculate the sum of odd numbers from 1 to 7820, 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 = (3910 ÷ 2) × (2 × 1 + (2 × (3910 - 1))
sum = 1955 × (2 + 7818)
sum = 1955 × 7820
sum = 15288100
Sum of odd numbers from 1 to 7820 = 15288100
Step 3) Calculate the average of odd numbers from 1 to 7820
Almost done! Now we can calculate the average of odd numbers from 1 to 7820 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 = 15288100 ÷ 3910
Average = 3910
Average of odd numbers from 1 to 7820 = 3910
