What is the average of odd numbers from 1 to 313? Here we will show you how to calculate the average of odd numbers from 1 to 313.
To find the average of the odd numbers from 1 to 313, we first calculate how many odd numbers there are from 1 to 313. Then, we calculate the sum of odd numbers from 1 to 313. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 313, and the odd numbers within that range are from 1 to 313. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 313.
Step 1) Calculate the total number of odd numbers from 1 to 313
Here we calculate the total number of odd numbers from 1 to 313 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 = (313 - 1 + 2) ÷ 2
tot = 314 ÷ 2
tot = 157
Total odd numbers from 1 to 313 = 157
Step 2) Calculate the sum of odd numbers from 1 to 313
To calculate the sum of odd numbers from 1 to 313, 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 = (157 ÷ 2) × (2 × 1 + (2 × (157 - 1))
sum = 78.5 × (2 + 312)
sum = 78.5 × 314
sum = 24649
Sum of odd numbers from 1 to 313 = 24649
Step 3) Calculate the average of odd numbers from 1 to 313
Almost done! Now we can calculate the average of odd numbers from 1 to 313 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 = 24649 ÷ 157
Average = 157
Average of odd numbers from 1 to 313 = 157
