| Abstract: | This paper first introduces the concept of difference equation and presents the ordinary solution of first order difference equation xn 1=axn b and the special solution of the provided initial condition x1=c.Then it offers the ordinary solution of second order difference equation xn 2=axn 1 bxn and the special solution of the provided initial condition x1=m1,x2=m2.Finally it gives a detailed discussion to their application in probability theory. |
