<p >Problem:</p>
|
|
<p >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: <code>1,2,3,5,8,13,21,34,55,89,..</code> By considering the terms in the Fibonacci sequence whose values do not exceed n, find the sum of the even-valued terms. e.g. for n=10, we have {2,8}, sum is 10. </p>
