Simple Number Problem

[sdhalepaska]

What does the following list of numbers have in common and what would the next number be:

2, 5, 5, 4, 5, 6, 3, 7, X

[DeMan]

The next number is 6.....
If that is correct I can explain why, but others might like a go first.....

That is correct. Go ahead and explain it if you want. I would be interested to see hear how you figured it out...

[DeMan]

the number of bars on an LED/LCD (display) required to display different numbers.....

eg

1 = |
    |   
(2 bars) etc.....
 

[DeMan]

What about :
2,1,2,2,2,1,2,2,X,Y,Z

(if you get all 3 I'll assume you understand why!!)

[sdhalepaska]

What about :
2,1,2,2,2,1,2,2,X,Y,Z

(if you get all 3 I'll assume you understand why!!)

I would guess 2, 2, 2 but my guess would be based on a hope that you have one too many 2s in your question.

[DeMan]

'fraid that's not the answer, and I double checked, there is no extraneous digit......

[buddykid]

x=2
y=1
z=2

The pattern : 2122

2,1,2,2,2,1,2,2,X,Y,Z

(if you get all 3 I'll assume you understand why!!)

2
1
3

is the answer,

i thought it was some binary code to start of with but it is much simpler

i do actually know the answer, i didnt pull these numbers from thin air
