Okay, I can understand the confusion here. Let's look at the equation: {[(50 + 1) / 2] X 50} X 16 = 20,400 Now in word form. The first 50 is the fiftieth term in the arithmetic sequence of "an=1+n". The 1 is the first term in that sequence. As you'll recall from your high school math, the sum...

He phrased it in a way with which you may not be familiar. This is arithmetic sequence addition here. It will make more sense in this form: [50 X (50 + 1) / 2] X 16 = 20,400

Am I the only one who read DaGuy's post?

As already stated, it is to prevent us from letting one bulb burn out.

Are you saying DaGuy isn't right? His answer looked pretty solid to me. What's wrong with his reasoning?

Indeed they have been trained to ride bicycles. Although bears don't hibernate. They just enter a deep sleep that lasts for ... weeks. Points to Maruno in a moment here...

Check back in 2040 when I'm President. MY coin will be perfectly balanced. ;)

He'd be effectively unconscious (by my definition of the word, anyway).

No it isn't. I split a pile of fifty into two groups. I weigh ONE of the two. That tells me which of the two contains the light bag.

It can't mean "not a large enough number" because he asked for the lowest. I effectively showed how it could be done in six and he said that was not the answer. Therefore there must be a lower answer.

"Wrong" means "Not good enough".

Tkwiget, I already got it down to six.

A Chinese circus performer is leaving the tent after a very successful performance in America when suddenly he decides to defect. He rides his bicycle for eight miles before laying down to go to sleep. The police do not find him for quite a while. When they finally do find him, three weeks...

That can't be it.

Maruno had already figured out how to pay the links and how many breaks in the bracelet were necessary. He was just forgetting one break already existed so there wouldn't have to be a cut there. As far as I'm concerned, he gets the reward.

It is a chain with 7 links together, but what you're forgetting is that it's a BRACELET. Bracelets have to come off, and this a gold bracelet, not an elastic one. Gold bracelets have latches that allow you to take them off. So once it's removed, picture it not as a loop but simply as a chain...

She pays one link per night. One night at a time.

Very close. Try again.

^Wrong. Try again.

That happens a lot. Almost all twins are separated in age by at least a few seconds.
