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.
x = 0;
k = 1;
while fibonacci(k) <= 4000000
if fibonacci(k)/2 - floor(fibonacci(k)/2) == 0
x = x + fibonacci(k);
end
k = k + 1;
end
x
