Question: Finding functions from recursive formulas

Hi,

 
I have the following Recursive formulas:
 

x[i+1]:= x[i]+h*(r*x[i+1]*(1-(x[i+1]+y[i])/k)-(1-u__1[i])*beta*v[i]*(x[i+1]/(x[i+1]+y[i])));

 y[i+1]:= y[i]+h*(((1-u__1[i])*beta*v[i]*x[i+1]/(x[i+1]+y[i+1]))-a*y[i+1]);

 v[i+1]:= v[i]+h*(((1-u__2[i])*gamma*y[i+1]-mu*v[i+1]);

where

 

x[0]:=140: y[0]:=145:v[0]:=18:

 mu:=0.73:
 gamma:=250:
 beta:=0.0014:

h:= 1:

 r:=0.01:
  a:=0.0693:
 k:=340:

 

I want to find x[1],y[1],v[1] and x[2],y[2],v[2] ,.... in maple

please help me.

Regards
