## Question

I got this idea from brhan's sequence.

A set of numbers is given below:

1,2,3,2,1,2,3,4,2,1

Another set of numbers is given below:

8,4,12,4,8,4,12,2,4,8

There is a certain relationship between these two sets of numbers.Can you find the relationship?

If nobody finds an answer I will post a hint.

The easy answer is that 1 corresponds with 8, 2 with 4, 3 with 12, and 4 with 2. That is the relationship.

I'm not wrong, but still not what you wanted i think.

One that I think is more what you had in mind...

It works for all except the 3rd to last term... But 8/x. I know it's not completely right so i'm still hammering out some other variations.

Is this close at all to what you want? Or am i going completely the wrong direction.

Sorry.No , what i have in mind is something different.

Try of converting the first Set of nos. into second set or vice-versa.

Do not think in terms of very complex formulae

I think I have it.

0 -> 0

Oops. Nope. My answer would make 4 -> 8.

Still thinking.

Does a clock help?

My reasoning is something different.

a different base

I think this one is difficult. Dono which direction to go ....

That makes 12[hex] = 18[decimal] the others are the same in hex or decimal.

2 -> 4
3 -> 18
4 -> 2
`1 ->  8`
I'm missing something. Or perhaps the OP is missing a "decimal" point, and the relationship is

8/2 -> 4
8/3 -> 1.8[hex] -> 2.666[dec] ... kind of? [nah]
8/4 -> 2
`8/1 ->  8`

A huge SORRY to everyone who have tried to solve this one . I made a very , very silly mistake. I found my mistake only when I went through Bonanova's , reply.

CLARIFICATION:

First set:

1,2,3,2,1,2,3,4,2,1

Second set:

8,4,C,4,8,4,C,2,4,8

Again sorry!!!

Well, the first is a pattern of numbers that go up to three, then back to one, then up to four then skips three and goes back to one.

The second kinda goes with that pattern, but 8 replace 1, 4 replaces 2, 12 replaces 3, and 2 replaces 4.

Uhhh... that's about as far as I get.

With bases...

the first set would remain the same. Octet.. quartet.. binary? The four and two replace each other for some reason.

=/ I'm not so good at these things, guess I will have to wait for the answer as well.

The second series numbers are binary reverse of first series numbers.. if you consider four binary digits..

for example:

1=0001, in reverse order 1000=8

2=0010, in reverse order 0100=4

3=0011, in reverse order 1100=12(C )

4=0100, in reverse order 0010=2

12 is also ok!Excellent puzzle!! <_<

1100=C not 12.

But you reasoned it out first.So congratulations.

Sorry storm no offence meant.I only posted it bacause Bononova and brhan must have spent a considerable trying to solve this.So thanks sgain.

It can be considered also as 12..becoz..

In decimal..1100 is 12...why worry?

I agree with you.But I gave a clue relating to hexadecimal system.

Storm, totally agree.

Gray cells, great puzzle.

Gray cells, great puzzle.

Thanks , bononova.But still I am not entirely in the clear.If it is hex how can 12 be equal to 1100.

But the original numbers [in decimal] work ok, right?

C[hex] and 12[dec] are both 1100[bin].

Yes . They are the same in decimal.But not in hex.In hex , if I am not mistaken 12=10010.
