Question:Rational Numbers

x_1 = 1;

x_n = 1/2 (x_n-1 + 3/x_n-1 ) for n>=2

Is there a maple command to check if the above statement is rational, eventhough it is obvious enough?

I tried to evaluate x_2 using subs(n=2, x_n) but keep getting an expression in terms of x_1. Using evalf(x_2), the result was x_2.

I'm very new to maple, so please help :(
