Plotting a sequence using stem()

How can one plot this sequence using the command stem? I have tried a lot of combinations of this, but I guess I don't quite grasp the concept of computing elementwise:

My code (which doesn't work):

x = linspace(1,50,50) % I'm computing the first 50 terms

y = sqrt((3+2*x.^2)/(8*x.^2+x))

stem(y)

Thank you.

You need to vectorise the division as well:

y = sqrt((3+2*x.^2)./(8*x.^2+x));
                   ↑

and ideally plot both your independent and dependent variables:

stem(x, y)
