What is the average of even numbers from 1 to 6489? Here we will show you how to calculate the average of even numbers from 1 to 6489.
To find the average of the even numbers from 1 to 6489, we first calculate how many even numbers there are from 1 to 6489. Then, we calculate the sum of even numbers from 1 to 6489. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 6489, and the even numbers within that range are from 2 to 6488. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 6488.
Step 1) Calculate the total number of even numbers from 1 to 6489
Here we calculate the total number of even numbers from 1 to 6489 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 = (6488 - 2 + 2) ÷ 2
tot = 6488 ÷ 2
tot = 3244
Total even numbers from 1 to 6489 = 3244
Step 2) Calculate the sum of even numbers from 1 to 6489
To calculate the sum of even numbers from 1 to 6489, 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 = (3244 ÷ 2) × (2 × 2 + (2 × (3244 - 1))
sum = 1622 × (4 + 6486)
sum = 1622 × 6490
sum = 10526780
Sum of even numbers from 1 to 6489 = 10526780
Step 3) Calculate the average of even numbers from 1 to 6489
Almost done! Now we can calculate the average of even numbers from 1 to 6489 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 = 10526780 ÷ 3244
Average = 3245
Average of even numbers from 1 to 6489 = 3245
