**Problem 2**

*Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:*

*1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …*

*By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.*

**Discussion**

C based languages have such similar syntax that this is a copy from the C# solution. Of course, I had to remove the type declarations because it’s not strongly typed. Oh, and I guess I do output to HTML.
