right

(10*10-10)/2 = 45

(45*45-45)/2 = 990

(990*990-990)/2 = 489555

Re: Riddle game

Hint 2: If you slightly change the rules of counting you get that row:

1 1 2 5 12        ( instead of 1 1 2 7 18 )

Probably you'll need the help of wikipedia or similar sites. It's hard to count it yourself.

Pft, U R just 2 dumb. That's why.

misstake cheating isnt allowed

In that special case, I wouldn't consider looking it up at Wikipedia as cheating. That's what I did. You must know, what to look for. The answer is not on the Tetris page itself.  And believe me, it is really hard to not miscount. As a reminder, the riddle was: Find the next number

1 1 2 7 18 ??

Re: Riddle game

Sorry, I've failed. I'll post the solution and the next riddle.

I was looking for how many mutually different polyominoes exist with a certain number of squares. Whereby the polyominoes could only be rotated in the plane, thus the mirrored polyomino can be different. For example in Tetris L and J pieces are different.

There's 1 monomino, 1 domino, 2 trominoes, 7 tetrominoes (Tetris pieces) and 18 pentominoes. Here the latter:

Next in line are the hexominoes:

The 10 red colored pieces have a mirror axis, so their mirrored counterpart is the same. Thus 10 + 2*25 = 60 mutually different hexomioes exist, if you just rotate in the plane.

NEW RIDDLE! This time it's easier. Complete the code:

001100010010011110100001101101 ??????

Re: Riddle game

indeed, trial and misstake!

Formular would have looked like this:

  • variables: x  = number of cows, y = number of chickens
  • linear equation system:
  • 2*x + 2*y = 40 (eye formular)
  • 4*x + 2*y = 64 (leg formular)

Re: Riddle game

OK here we go: Combining the numbers 6, 4, 3 and 1, you can create all integer numbers between 1 and 33. With combining I mean using the 4 basic arithmetic operations (addition, subtraction, multiplication, division). You must use each number exactly 1 time, but you can rearrange the order (and use brackets). For example we have

  • 1 = (6+1)/(4+3)
  • ...
  • 24 = ???
  • ...
  • 31 = (6+4)*3+1
  • 32 = (6+3-1)*4
  • 33 = (6+4+1)*3

I want you to create the number 24!

Re: Riddle game

whats the point of a mathematical question which u can only solve by try & error?

maybe thats just me, but when i hear "riddle thread" i think about something that can be solved within a few minutes with hard thinking or logical thinking. 

anyway, may the geekiest geek win!

Re: Riddle game

LOL t0x this can be solved in just a few minutes.

At first, you might try to do an addition or subtraction as last operation. But you will notice pretty fast, that you cannot combine the other 3 numbers to 18, 20, 21, 23, 25, 27, 28, 32. So it's all about finding a proper factorization of 24.

24 = 6*4 = 8*3 = ???

At this point, it is more about logic than you might think.

This was my first hint BTW.

Re: Riddle game

Cfb, your solution process is not allowed. 6,4,3,1 are numbers and shouldn't be treated as digits ( 1,4->14 is not allowed).

I was able to solve it within 3 minutes. So I thought this wouldn't be too hard. But meh, yet another hint:

You have to use division twice.

That means 2 of the 3 operations are divisions ( like 6/3 = 2 resp. 6:3 = 2 ).
