Lets see who can figure this one out.

Int he picture below you can take the square and cut it into 4 pieces to form the rectangle on the bottom. Show me how you would cut the square. No cheating with google or any other search engine. Do your own work..... The first to solve this one will post the next Brain twister.....

I'm sorry, I just can't find the nude babe anywhere.

How do you go from 64 squares to 78 squares with 4 cuts?

4. ### orangelloNew Member

Ditto, is 3D, like layers lifted or stacked allowed?

5. ### cpttango30New Member

Ok fixed it. Now it will work sorry about that.

Same question, 64 is not 65.

Howsabout, 1,2,6,42,1806,? What is the next number in the series (where the ? is)?
Nice & simple.

It can be done. I am telling you it can be done.

Oh and it is 3,263,422

Something ain't right...
I can't account for the first digit...

Nevermind...i got it.

X= y*(y+1)
where y= previous number in sequence!!

Of course this is disingenuous because 0 is not included in the original sequence.
0 * (0+1)=1
1*(1+1)=2
2*(2+1)=6
6*(6+1)=42
46*(46+1)=1806
1806*(1806+1) = 3263442

sorry about the zero, this was second-hand from my memory. So, do you make up the next one until somebody gets Tango's?

I'm still working on it but I'm actually doing work to so only half focusing on it. The key is going to be creating the 65th block from edges of the other pieces. Example, if you can make a pattern save for the block in the center, then you have created the block in the center. Hence 64 blocks make 65.

Or so I think, dunno, I've tried all the logical ways I can think of.

May wanna check that.

0*1=0

46*47=2162

but,

42*43=1806

d'oh!

This is what I get for going too fast. Simplified, I believe that should be:

N=X*(X+1) {where X is the previous number in the series}
ergo:
1,
1*(2) = 2,
2*(3) = 6,
6*(7) = 42,
42*(43) = 1806,
1806*(1807) = 3263442

I guess we have to assume that the first number does not adhere to the formula...However, the progression is the same if we call it:

N=(X^2)+X {where X is the previous number in the series. Damn circular reference.}

14. ### skullcrusherNew Member

as in any sequence, the first number acts as a start of the sequence. The sequence could have been started with any number, the number itself being undefined. It could even be a decimal.

gotcha...

It's been a long time since I did this crap.

16. ### cpttango30New Member

Come on you guys. Lets work them brain cells a little.

I will give you a hint Fib...

I cheated and google'd the answer. Here's another hint, don't listen to my first post about how to solve it.
