What is the average of even numbers from 1 to 1813? Here we will show you how to calculate the average of even numbers from 1 to 1813.
To find the average of the even numbers from 1 to 1813, we first calculate how many even numbers there are from 1 to 1813. Then, we calculate the sum of even numbers from 1 to 1813. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1813, and the even numbers within that range are from 2 to 1812. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1812.
Step 1) Calculate the total number of even numbers from 1 to 1813
Here we calculate the total number of even numbers from 1 to 1813 by entering the first and last even number in the sequence into our formula. Here is the formula and the math:
tot = (last - first + 2) ÷ 2
tot = (1812 - 2 + 2) ÷ 2
tot = 1812 ÷ 2
tot = 906
Total even numbers from 1 to 1813 = 906
Step 2) Calculate the sum of even numbers from 1 to 1813
To calculate the sum of even numbers from 1 to 1813, you enter the total even numbers (tot) from Step 1 and the first even number in the sequence into our formula. Here is the formula and the math:
sum = (tot ÷ 2) × (2 × first + (2 × (tot - 1))
sum = (906 ÷ 2) × (2 × 2 + (2 × (906 - 1))
sum = 453 × (4 + 1810)
sum = 453 × 1814
sum = 821742
Sum of even numbers from 1 to 1813 = 821742
Step 3) Calculate the average of even numbers from 1 to 1813
Almost done! Now we can calculate the average of even numbers from 1 to 1813 by dividing the sum of even numbers from Step 2 by the total even numbers from Step 1. Here is the formula, the math, and the answer:
Average = sum ÷ tot
Average = 821742 ÷ 906
Average = 907
Average of even numbers from 1 to 1813 = 907
