Your question is essentially "Does povray have scripting capability?",
so perhaps belongs in povray.newusers...

Anyway:

#declare loop = 0; //counter
#declare shift = 0; //cumulative size

#while (loop < 100)

 #declare shift = shift + (((loop-1)+1)/2);

    cylinder {<0,0,0>,<0,1,0>,0.2 scale (loop+1)/2 translate <0,shift,0>
pigment {color rgb 0.8}}

    #declare loop = loop + 1;
    #end
