    Small puzzle

    Find the next number in the sequence.

    Hint: I'm breaking the rules a bit here.

    911 sounds like a Porsche
    636 could be a Mazda, but the the others, I have no clue

    Ha! I've stumped you all, and all I needed to do was cheat.

    The formulae I'm using is n*a where n is the position (1 being the rightmost) and a the value. So:

    385 =
    3*3 + 8*2 + 5*1
    9+16+5
    30

    911 =
    9*3 + 1*2 + 1*1
    27 + 3 + 1
    30

    Get the pattern yet?

    Instead of changing the number I changed the method, I said I broke the rules.

    hmmm...

    I think u distinctly said:
    "Find the next number"
    Which, simply put, must mean that there is some relationship between the terms that allows you to find the next one.
    However, you did not supply what the next term is.
    But, whatever it is, it can be right, cos you can build a fuction for it.
