Euler 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.

The Answer is...4,613,732!! you can find the answer for the sum of all the even Fibonacci numbers not exceeding any number by typing whatever number you want into the box and clicking click to compute.
