? = 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
592
592
592
592
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.
592
592
the repeating sequence is *4 +4
its 592
pattern is: x4 then +4
592…..*4+4
592
The sequence is *4, +4, *4, +4, etc.. Missing number is 592.
(You’re getting too easy RK! :P)
592
The pattern is x4, +4, x4, +4…
hey tht one was easy….u multiply nd add 4alternatively…..so the answer is 592
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
592.
592…
592
think 4s
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.
answer is 592.
a x4, +4 sequence
8×4 = 32
32 + 4 = 36
36 x 4 = 144
144 + 4 = 148
148 x 4 = 592
592 + 4 = 596
This took about 4 seconds ;p
592
592
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
592,
by unanimous consensus
ok, will try to throw some tough ones out next week!
pattern: *4, +4, *4, +4, ….
There for missing number is 592 (148*4)
too easy - it is cover the red circle with 5 smaller circles I can’t get
