    ? = 592
    Because:
    8 (Ball 1) x 4 = 32 (Ball 2) + 4 = 36 (Ball 3) x 4 = 144 (Ball 4) + 4 = 148 (Ball 5) x 4 = 592 (? Ball) + 4 = 596 (Final Ball)

    Without a doubt.
    u(0)=8
    For odd terms:
    u(n)=u(n-1)*4
    For even terms:
    u(n)=u(n-1)+4

    Sequence alternates between multiplying by 4 and adding 4.

    Eg
    8 x 4 = 32
    32 + 4 = 36
    36 x 4 =144
    144 + 4 = 148 … and so on

    592 would be the missing number.

    The pattern is times four, plus four, times four, plus four…

    592. Multiply by 4, then add 4. Repeat.

  17. suineg | Guest

    one answer can be this:
    Is a series: * 4 ,+4 (repeated to infinity, but only see till 596)
    1) 8*4=32+4=36*4=144+4=148*4=592+4=596

    592 that was easy and i mean really easy. i barly had to think at all. the pattern is multiply by four, add four. for the ? you had to multiply and I didn’t feel like doing that. I just looked at 596 and subtracted 4.


  23. Poelo | Guest

    answer is 592.

    a x4, +4 sequence


  24. Alex | Guest

    8×4 = 32
    32 + 4 = 36
    36 x 4 = 144
    144 + 4 = 148
    148 x 4 = 592
    592 + 4 = 596

  27. rajjo | Guest

    4 + 4 =8
    8 x 4 =32
    32 +4 =36
    36 x 4=144
    144 +4=148
    148 x 4 =592
    592 + 4 =596

    Answer: 592

    2nd number = 1st number * 4
    3rd number = 2nd + 4 and so on.

    So 6th number = 5th number * 4
    i.e. 148*4=592
