    Re: Number Pattern

    Hello, KayPee!

    The numbers in the brackets follow the same pattern: .[2, 6, 24] .[3, 2, 15] .[7, 5, X]

    Find the value of X.

    The pattern seems to be: . [a,\,b,\,3(a+b)]

    Therefore: . [7,\,5,\,36]

    Thanks from HallsofIvy, topsquark and KayPee

    Just curious Soroban. Did you intuit the relation or did you have an analytical way?

    I can't be certain but I suspect Soroban tried a number of calculations until one worked.

    I have gotten complaints about constantly telling people on this and other boards to try something!
