geometric progression and multiply by a common variable, help me pls.

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]))
