My approach:
x = 1:20;
odv = x(rem(x,2)==1);
n = 10; % Length Of Series
oddrnd = odv(randi(length(odv),1,n));

I didn’t forget, and I considered the (2*n+1) possibility as well. I simply chose the most obvious solution.

I would argue that 1:2:20 is more obvious and beginner friendly than your solution.

How about?
(randi(10, 1, serieslength) - 1) * 2 + 1; %replace serieslength by actual length of series.
That is generate random integers between 0 and 9, multiply by 2 and add 1.

It generates odd numbers between 1 and 19. It's not particularly hard to figure out how to do it for other ranges
halfrange = (maxrange - minrange) / 2; %replace max and min by actual values, values must be odd.
(randi(halfrange, 1, serieslength) - 1) * 2 + minrange;

for K = 1 : 5
scalar = randi([0 65535]) * 2 + 1
end
