What is the formula of finding the sum of a series of even numbers?

You didn't say the series (I prefer to use the word sequence) of even numbers are consecutive even numbers, or even more generally an arithmetic sequence. If we are not given any information about the sequence other than that each member happens to be even, there is no formula for that other than the fact that you can factor out the 2 from each member and add up the halves, then multiply by 2:
2a + 2b + 2c = 2(a + b + c). If the even numbers are an arithmetic sequence, you can use the formula for the sum of an arithmetic sequence. Similarly if they are a geometric sequence.

You cannot. There are infinitely many even numbers and their sum is not convergent.

There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
What is the sum of the fist 40 even numbers?
You can use the formula for the sum of an arithmetic series to calculate that quickly. (Of course, you can also type the numbers into Excel, and get the sum - but that doesn't scale well - e.g., it won't work well if you are then asked, for instance, to get the sum of the first million even numbers.)
What is the sum of even numbers less than 28?
Just do the additions. Or, if you want a shortcut, use the formula for an arithmetic series.

What is the method of finding prime numbers?
their isn't a formula or method for finding prime numbers. Prim numbers are just all the numbers that have only two factors not including zero. Like 2 is a prime number because it can be multiplied by 1 and two two get it but not all even numbers are prime 2 is the only one another example is 5 because to get 5 you can only multiply it by 1 and 5

What is the sum of the first five positive even numbers?
2 + 4 + 6 + 8 + 10 = 30 In general, the sum of the first n even numbers is n(n+1). Replacing n with 5 we have 5x6 which equals 30 as we found by direct calcuation. The formula is nice when you have many numbers. For example, finding the sum of the first 100 positive even numbers would be a PAIN! But using the formula is it simply 100x101.
What Mr.Crab Crab patty formula?
There can be no formula because it is not a compound but a mixture. And, if you enjoy them don't even think about finding out details of their composition!
What does it mean when you line up a set of numbers from the smallest to largest then divide by 2 if you have an even set of numbers?
You are finding the mean of the set of numbers.
What 3 consecutive even numbers equals 300?
There are none. There are two odd numbers next to every even one, so finding 3 consecutive numbers of the same kind is impossible.
