What is the average of even numbers from 1 to 1403? Here we will show you how to calculate the average of even numbers from 1 to 1403.
To find the average of the even numbers from 1 to 1403, we first calculate how many even numbers there are from 1 to 1403. Then, we calculate the sum of even numbers from 1 to 1403. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1403, and the even numbers within that range are from 2 to 1402. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1402.
Step 1) Calculate the total number of even numbers from 1 to 1403
Here we calculate the total number of even numbers from 1 to 1403 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 = (1402 - 2 + 2) ÷ 2
tot = 1402 ÷ 2
tot = 701
Total even numbers from 1 to 1403 = 701
Step 2) Calculate the sum of even numbers from 1 to 1403
To calculate the sum of even numbers from 1 to 1403, 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 = (701 ÷ 2) × (2 × 2 + (2 × (701 - 1))
sum = 350.5 × (4 + 1400)
sum = 350.5 × 1404
sum = 492102
Sum of even numbers from 1 to 1403 = 492102
Step 3) Calculate the average of even numbers from 1 to 1403
Almost done! Now we can calculate the average of even numbers from 1 to 1403 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 = 492102 ÷ 701
Average = 702
Average of even numbers from 1 to 1403 = 702
