Centering multiple objects

I need to calculate how to center multiple objects within a certain width.

I have between 1 and 6 letters. Depending on how much letters are displayed, they have to be centered together within display.contentWidth.

Something like:

[lua]

for i=1,#LetterTable do

     Tiles[i].x = _W / 2 - (Number * 102)  

      Number = Number + 1

end

[/lua]

Above code doesn’t work, unless youre displaying only 1 letter.

Since I’m not very good at this, maybe someone can help me out here?

Thanks in advance!

Anyone?
