    Too easy.

    Write it down and watch carefully the relation between the numbers.

    The point is the kid learning how to do this himself. :)

    If you'd done that in school, you wouldn't know anything. (Which is a
    possibility; I don't know.)

    Doesn't giving the answer avoid having to get the 'how'? Not posting
    either was the point :)

    OK> Here's an answer received from "Math Forum@Drexel".
    Does this help?

    120 60 180 90 666 666 405. Obviously, the sequence is the polynomial

    (2990160 - 6888924 x + 5902372 x^2 - 2446935 x^3 + 525955 x^4 - 56181
    x^5 + 2353 x^6) / 240


    evaluated at x=1, x=2, x=3, etc.

    1. sum of two preceding (180 + 90 = 270)
    2. result divided by 2 (270/2 = 135)

    1. sum of two preceding (270 + 135 = 405)
    etc.

    It's simpler than that, don't need the addition, although it's an
    alternative option it wasn't the 1 I saw right away.

    I started with step 2 in place of your step 1. Then see what happens :)

    Polynomial? This is a standard question on a college entrance exam and
    you'd fail miserably.

    Seems right...

    Even more, any number can be considered the next number,
    it is sufficient to choose an adequate Lagrange interpolating
    polynomial."

    You mean...

    1.5 * 90 = 135
    1.5 * 180 = 270

    ?
