What is the average of even numbers from 1 to 1705? Here we will show you how to calculate the average of even numbers from 1 to 1705.
To find the average of the even numbers from 1 to 1705, we first calculate how many even numbers there are from 1 to 1705. Then, we calculate the sum of even numbers from 1 to 1705. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1705, and the even numbers within that range are from 2 to 1704. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1704.
Step 1) Calculate the total number of even numbers from 1 to 1705
Here we calculate the total number of even numbers from 1 to 1705 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 = (1704 - 2 + 2) ÷ 2
tot = 1704 ÷ 2
tot = 852
Total even numbers from 1 to 1705 = 852
Step 2) Calculate the sum of even numbers from 1 to 1705
To calculate the sum of even numbers from 1 to 1705, 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 = (852 ÷ 2) × (2 × 2 + (2 × (852 - 1))
sum = 426 × (4 + 1702)
sum = 426 × 1706
sum = 726756
Sum of even numbers from 1 to 1705 = 726756
Step 3) Calculate the average of even numbers from 1 to 1705
Almost done! Now we can calculate the average of even numbers from 1 to 1705 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 = 726756 ÷ 852
Average = 853
Average of even numbers from 1 to 1705 = 853
