## euler-002
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.

----------


$perl -e '($a, $b) = (1, 2); while ($b <= 4000000) { $t += $b if $b %2 == 0; ($a, $b) = ($b, $a + $b); } print "$t\n";'
