real analysis - Recursive relation in the square root form.

I apologize if this has been asked before, but I have been struggling to show the convergence and the limit value of the following recursive relation:




xn+2=xnxn+1 with initial values x1=a and x2=b for $0




I showed by induction that $ x_{2n-1}. I know that if I could show that lim, then this implies convergence. However, I could not see the pattern. Moreover, I could not find the actual limit either. Thanks for any help!
