What is the average of odd numbers from 1 to 545? Here we will show you how to calculate the average of odd numbers from 1 to 545.
To find the average of the odd numbers from 1 to 545, we first calculate how many odd numbers there are from 1 to 545. Then, we calculate the sum of odd numbers from 1 to 545. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 545, and the odd numbers within that range are from 1 to 545. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 545.
Step 1) Calculate the total number of odd numbers from 1 to 545
Here we calculate the total number of odd numbers from 1 to 545 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 = (545 - 1 + 2) ÷ 2
tot = 546 ÷ 2
tot = 273
Total odd numbers from 1 to 545 = 273
Step 2) Calculate the sum of odd numbers from 1 to 545
To calculate the sum of odd numbers from 1 to 545, 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 = (273 ÷ 2) × (2 × 1 + (2 × (273 - 1))
sum = 136.5 × (2 + 544)
sum = 136.5 × 546
sum = 74529
Sum of odd numbers from 1 to 545 = 74529
Step 3) Calculate the average of odd numbers from 1 to 545
Almost done! Now we can calculate the average of odd numbers from 1 to 545 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 = 74529 ÷ 273
Average = 273
Average of odd numbers from 1 to 545 = 273
