How could I generalize some numbers, for example (20, 20 * sqrt (2), 28.2 * squr (2) and so on) as a geometric progression and then multiply by a common variable and get all possible results, e.g. (20 * B), ((20 * sqrt (2)) * B), ((28.2 * squr (2)) * B)

So, you want this?
B = 3;
C = B*20*sqrt(2).^(0:10)
C =
Columns 1 through 9
60 84.853 120 169.71 240 339.41 480 678.82 960
Columns 10 through 11
1357.6 1920

very well done.
i did this, but your way is better
q = sqrt(2);
DiscStN = 20;
DiscSt.N = fix((20*[1,q,q^2,q^3,q^4,q^5,q^6,q^7]))
