What is the average of odd numbers from 1 to 438? Here we will show you how to calculate the average of odd numbers from 1 to 438.
To find the average of the odd numbers from 1 to 438, we first calculate how many odd numbers there are from 1 to 438. Then, we calculate the sum of odd numbers from 1 to 438. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 438, and the odd numbers within that range are from 1 to 437. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 437.
Step 1) Calculate the total number of odd numbers from 1 to 438
Here we calculate the total number of odd numbers from 1 to 438 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 = (437 - 1 + 2) ÷ 2
tot = 438 ÷ 2
tot = 219
Total odd numbers from 1 to 438 = 219
Step 2) Calculate the sum of odd numbers from 1 to 438
To calculate the sum of odd numbers from 1 to 438, 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 = (219 ÷ 2) × (2 × 1 + (2 × (219 - 1))
sum = 109.5 × (2 + 436)
sum = 109.5 × 438
sum = 47961
Sum of odd numbers from 1 to 438 = 47961
Step 3) Calculate the average of odd numbers from 1 to 438
Almost done! Now we can calculate the average of odd numbers from 1 to 438 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 = 47961 ÷ 219
Average = 219
Average of odd numbers from 1 to 438 = 219
