The answer to what is the sum of the first positive even numbers is 930. It doesn't mean that you add all the even numbers up until you reach the number 30. In fact, since you have to get the sum of the even numbers, you have to add all even numbers until you get to the number 60.
To find the sum of all even numbers between 10 and 20, we first need to identify the even numbers in that range. The even numbers between 10 and 20 are 10, 12, 14, 16, and 18. Adding these numbers together, we get 10 + 12 + 14 + 16 + 18 = 70. Therefore, the sum of all even numbers between 10 and 20 is 70.
Find the average. That is, add all of the even numbers together, then divide that by the number of even numbers.
Start with 2, then add 2 at a time, until you reach a million. This will give you all the even numbers.
The sum of all even numbers between 10 and 20 can be found by adding the even numbers in that range. The even numbers between 10 and 20 are 12, 14, 16, and 18. Adding these numbers together, 12 + 14 + 16 + 18 equals 60. Therefore, the sum of all even numbers between 10 and 20 is 60.
102*25=2550

288. All multiples of 9 will have digits that add to a multiple of 9. To get a multiple of 9 to be all even, you need to get them to add to 18, since no set of even numbers will add up to 9. 288 is the lowest multiple of 9 to be able to add to 18. ■
The even numbers between 41 and 47 are 42, 44 and 46.
Apart from 2, all even numbers are composite. So the question is equivalent to all even numbers between 40 and 50. And these are ... ? 42, 44, 46 and 48.
