What is the average of even numbers from 1 to 1213? Here we will show you how to calculate the average of even numbers from 1 to 1213.
To find the average of the even numbers from 1 to 1213, we first calculate how many even numbers there are from 1 to 1213. Then, we calculate the sum of even numbers from 1 to 1213. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1213, and the even numbers within that range are from 2 to 1212. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1212.
Step 1) Calculate the total number of even numbers from 1 to 1213
Here we calculate the total number of even numbers from 1 to 1213 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 = (1212 - 2 + 2) ÷ 2
tot = 1212 ÷ 2
tot = 606
Total even numbers from 1 to 1213 = 606
Step 2) Calculate the sum of even numbers from 1 to 1213
To calculate the sum of even numbers from 1 to 1213, 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 = (606 ÷ 2) × (2 × 2 + (2 × (606 - 1))
sum = 303 × (4 + 1210)
sum = 303 × 1214
sum = 367842
Sum of even numbers from 1 to 1213 = 367842
Step 3) Calculate the average of even numbers from 1 to 1213
Almost done! Now we can calculate the average of even numbers from 1 to 1213 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 = 367842 ÷ 606
Average = 607
Average of even numbers from 1 to 1213 = 607
