Find the sum of all the even-valued terms in the Fibonacci sequence which do not exceed four million.

**Problem:**

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, …

Find the sum of all the even-valued terms in the sequence which do not exceed four million.

**My Solution:**

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Euler
{
class Problem2 : IProblemBase
{
//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, ...
//Find the sum of all the even-valued terms in the sequence which do not exceed four million.

{
int result = 2;
int runningTotal = 0;
int sequenceOne = 1;
int sequenceTwo = 2;
while (sequenceTwo <= 4000000)
{
runningTotal = (sequenceOne + sequenceTwo);
sequenceOne = sequenceTwo;
sequenceTwo = runningTotal;
if (sequenceTwo % 2 == 0)
{
result += sequenceTwo;
}
}
return result.ToString();
}
}
}
