Need to automate this for sequential integer values of n.

What I need is the numerator of the function f(n) = a/b expressed as a fraction. Thus, I need the value of a. 

The series would be: 1, 1, 3, 5, 35, 63, 231 for n = 0, 1, 2, 3, 4, 5, 6.

The problem I’m having is that Mathcad Prime’s numerator function only applies to symbolic processing.

Like this?

Alan, 

Thanks!

Except the denominator should be 4^n. I’ll try it later.
