What is the average of odd numbers from 1 to 1280? Here we will show you how to calculate the average of odd numbers from 1 to 1280.
To find the average of the odd numbers from 1 to 1280, we first calculate how many odd numbers there are from 1 to 1280. Then, we calculate the sum of odd numbers from 1 to 1280. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 1280, and the odd numbers within that range are from 1 to 1279. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 1279.
Step 1) Calculate the total number of odd numbers from 1 to 1280
Here we calculate the total number of odd numbers from 1 to 1280 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 = (1279 - 1 + 2) ÷ 2
tot = 1280 ÷ 2
tot = 640
Total odd numbers from 1 to 1280 = 640
Step 2) Calculate the sum of odd numbers from 1 to 1280
To calculate the sum of odd numbers from 1 to 1280, 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 = (640 ÷ 2) × (2 × 1 + (2 × (640 - 1))
sum = 320 × (2 + 1278)
sum = 320 × 1280
sum = 409600
Sum of odd numbers from 1 to 1280 = 409600
Step 3) Calculate the average of odd numbers from 1 to 1280
Almost done! Now we can calculate the average of odd numbers from 1 to 1280 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 = 409600 ÷ 640
Average = 640
Average of odd numbers from 1 to 1280 = 640
