What is the average of even numbers from 1 to 1358? Here we will show you how to calculate the average of even numbers from 1 to 1358.
To find the average of the even numbers from 1 to 1358, we first calculate how many even numbers there are from 1 to 1358. Then, we calculate the sum of even numbers from 1 to 1358. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1358, and the even numbers within that range are from 2 to 1358. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1358.
Step 1) Calculate the total number of even numbers from 1 to 1358
Here we calculate the total number of even numbers from 1 to 1358 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 = (1358 - 2 + 2) ÷ 2
tot = 1358 ÷ 2
tot = 679
Total even numbers from 1 to 1358 = 679
Step 2) Calculate the sum of even numbers from 1 to 1358
To calculate the sum of even numbers from 1 to 1358, 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 = (679 ÷ 2) × (2 × 2 + (2 × (679 - 1))
sum = 339.5 × (4 + 1356)
sum = 339.5 × 1360
sum = 461720
Sum of even numbers from 1 to 1358 = 461720
Step 3) Calculate the average of even numbers from 1 to 1358
Almost done! Now we can calculate the average of even numbers from 1 to 1358 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 = 461720 ÷ 679
Average = 680
Average of even numbers from 1 to 1358 = 680
