1. ## Stopping and Turning back hands of time

It's a very nice puzzle. I agree now that I understand the OP a little more.

3. ## Getting the slant

Well the first one is fairly simple.
4. ## where's the plane?

No clue about how to come up with a formula, but I did draw it out. I didn't really think about the height of the plane though....oops Edit:bad tags
5. ## Liar Game BD

I think we pay back the money with flesh if we end up negative so we have to at least try to break even.

18. ## Can you find a closed form equation for the sequence?

This problem recently popped back into my head. In one of my college calculus classes while working on sequences we came across the sequence 0,0,1,1,2,2,3,3,4,4,... and if I remember correctly we were told there was no closed form equation for it. But, I found one and presented it to the class. a[n]=(2n-1+(-1)n)/4 n=0...infinity My question is: Is there a closed form equation to define the sequence 0,0,0,1,1,1,2,2,2,3,3,3....? If not, why not? Just wondering.

without claiming that nothing is something
