What is the average of odd numbers from 1 to 1209? Here we will show you how to calculate the average of odd numbers from 1 to 1209.
To find the average of the odd numbers from 1 to 1209, we first calculate how many odd numbers there are from 1 to 1209. Then, we calculate the sum of odd numbers from 1 to 1209. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 1209, and the odd numbers within that range are from 1 to 1209. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 1209.
Step 1) Calculate the total number of odd numbers from 1 to 1209
Here we calculate the total number of odd numbers from 1 to 1209 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 = (1209 - 1 + 2) ÷ 2
tot = 1210 ÷ 2
tot = 605
Total odd numbers from 1 to 1209 = 605
Step 2) Calculate the sum of odd numbers from 1 to 1209
To calculate the sum of odd numbers from 1 to 1209, 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 = (605 ÷ 2) × (2 × 1 + (2 × (605 - 1))
sum = 302.5 × (2 + 1208)
sum = 302.5 × 1210
sum = 366025
Sum of odd numbers from 1 to 1209 = 366025
Step 3) Calculate the average of odd numbers from 1 to 1209
Almost done! Now we can calculate the average of odd numbers from 1 to 1209 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 = 366025 ÷ 605
Average = 605
Average of odd numbers from 1 to 1209 = 605
