What is the average of even numbers from 1 to 1553? Here we will show you how to calculate the average of even numbers from 1 to 1553.
To find the average of the even numbers from 1 to 1553, we first calculate how many even numbers there are from 1 to 1553. Then, we calculate the sum of even numbers from 1 to 1553. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1553, and the even numbers within that range are from 2 to 1552. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1552.
Step 1) Calculate the total number of even numbers from 1 to 1553
Here we calculate the total number of even numbers from 1 to 1553 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 = (1552 - 2 + 2) ÷ 2
tot = 1552 ÷ 2
tot = 776
Total even numbers from 1 to 1553 = 776
Step 2) Calculate the sum of even numbers from 1 to 1553
To calculate the sum of even numbers from 1 to 1553, 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 = (776 ÷ 2) × (2 × 2 + (2 × (776 - 1))
sum = 388 × (4 + 1550)
sum = 388 × 1554
sum = 602952
Sum of even numbers from 1 to 1553 = 602952
Step 3) Calculate the average of even numbers from 1 to 1553
Almost done! Now we can calculate the average of even numbers from 1 to 1553 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 = 602952 ÷ 776
Average = 777
Average of even numbers from 1 to 1553 = 777
