How to put the dots in the centre?

Question

documentclass[10pt,a4paper]{article}

usepackage{amssymb}
usepackage{graphicx}

    A+B
    
    C+D
    
    D+E
    
    vdots
    Y+Z

I want the output like the dots should be placed below the plus sign.
But i am getting the dots aligned to the left, how can I fix it.

Here's a way to this :
begin{document}
$begin{array}{l@{~}c@{~}l}
A &+     &B
C &+     &D
  &vdots&
E &+     &F
end{array}$
end{document}

One way is use matrix as defined in amsmath package:
documentclass{article}
usepackage{amsmath}

begin{document}
    [
begin{matrix}
A   +   B   
B   +   C   
  vdots    [3pt]
Y   +   Z
end{matrix}
    ]
end{document}

or with array (based on the last solution stolen from deleted @campa answer):
documentclass{article}

begin{document}
    [
begin{array}[t]{r@{:}c@{:}l}
A & +   & B     
B & +   & C     
& vdots  &     [3pt]
Y & +   & Z   
end{array}    
    ]
end{document}

Result is in this particular case similar as before, however, now terms on left and right from + can have different lengths but math expressions are still centered at + sign.
