What is the average of even numbers from 1 to 2389? Here we will show you how to calculate the average of even numbers from 1 to 2389.
To find the average of the even numbers from 1 to 2389, we first calculate how many even numbers there are from 1 to 2389. Then, we calculate the sum of even numbers from 1 to 2389. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 2389, and the even numbers within that range are from 2 to 2388. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 2388.
Step 1) Calculate the total number of even numbers from 1 to 2389
Here we calculate the total number of even numbers from 1 to 2389 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 = (2388 - 2 + 2) ÷ 2
tot = 2388 ÷ 2
tot = 1194
Total even numbers from 1 to 2389 = 1194
Step 2) Calculate the sum of even numbers from 1 to 2389
To calculate the sum of even numbers from 1 to 2389, 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 = (1194 ÷ 2) × (2 × 2 + (2 × (1194 - 1))
sum = 597 × (4 + 2386)
sum = 597 × 2390
sum = 1426830
Sum of even numbers from 1 to 2389 = 1426830
Step 3) Calculate the average of even numbers from 1 to 2389
Almost done! Now we can calculate the average of even numbers from 1 to 2389 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 = 1426830 ÷ 1194
Average = 1195
Average of even numbers from 1 to 2389 = 1195
