? = 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)

592
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…

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.

22. Poelo | Guest

a x4, +4 sequence

23. Alex | Guest

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

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

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

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