What is the average of even numbers from 1 to 8003? Here we will show you how to calculate the average of even numbers from 1 to 8003.
To find the average of the even numbers from 1 to 8003, we first calculate how many even numbers there are from 1 to 8003. Then, we calculate the sum of even numbers from 1 to 8003. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 8003, and the even numbers within that range are from 2 to 8002. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 8002.
Step 1) Calculate the total number of even numbers from 1 to 8003
Here we calculate the total number of even numbers from 1 to 8003 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 = (8002 - 2 + 2) ÷ 2
tot = 8002 ÷ 2
tot = 4001
Total even numbers from 1 to 8003 = 4001
Step 2) Calculate the sum of even numbers from 1 to 8003
To calculate the sum of even numbers from 1 to 8003, 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 = (4001 ÷ 2) × (2 × 2 + (2 × (4001 - 1))
sum = 2000.5 × (4 + 8000)
sum = 2000.5 × 8004
sum = 16012002
Sum of even numbers from 1 to 8003 = 16012002
Step 3) Calculate the average of even numbers from 1 to 8003
Almost done! Now we can calculate the average of even numbers from 1 to 8003 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 = 16012002 ÷ 4001
Average = 4002
Average of even numbers from 1 to 8003 = 4002
