    I see:

    18 = 3 * (3+3)

    24 = 4 * (4+2)

    continue....

    Okay; what efforts have you made to find "the answer"?

    Also, is the entire string the "series", so you've been given this?

    . . . . .18, 3, 3, 24, 4, 2, 32, 2, ??

    Or are the rows indicating that these are number triples:

    . . . . .18, 3: 3
    . . . . .24, 4: 2
    . . . . .32, 2: ??

    ...and you're supposed to find the rule that was applied to the first two rows, and then apply that rule to the third row? Thank you!
