I gave up and checked the answer in the back of the book (er, on Wikipedia). I'm not sure what the protocol is at this point: If this much time has elapsed, should I go ahead and offer what I think the answer is, even though I kind of "cheated" to find it?
And if so, once I've done that, should that count as an official answer, leading to me asking the next question? Or it that a "fail", such that the original asker should ask another one?
