What is the average of even numbers from 1 to 1142? Here we will show you how to calculate the average of even numbers from 1 to 1142.
To find the average of the even numbers from 1 to 1142, we first calculate how many even numbers there are from 1 to 1142. Then, we calculate the sum of even numbers from 1 to 1142. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1142, and the even numbers within that range are from 2 to 1142. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1142.
Step 1) Calculate the total number of even numbers from 1 to 1142
Here we calculate the total number of even numbers from 1 to 1142 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 = (1142 - 2 + 2) ÷ 2
tot = 1142 ÷ 2
tot = 571
Total even numbers from 1 to 1142 = 571
Step 2) Calculate the sum of even numbers from 1 to 1142
To calculate the sum of even numbers from 1 to 1142, 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 = (571 ÷ 2) × (2 × 2 + (2 × (571 - 1))
sum = 285.5 × (4 + 1140)
sum = 285.5 × 1144
sum = 326612
Sum of even numbers from 1 to 1142 = 326612
Step 3) Calculate the average of even numbers from 1 to 1142
Almost done! Now we can calculate the average of even numbers from 1 to 1142 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 = 326612 ÷ 571
Average = 572
Average of even numbers from 1 to 1142 = 572
