How can i solve difference equations in mathematica.
I am doing a master in economics. Does anyone give some instructions
with
example.

Yes, Mathematica can indeed solve difference equations.  Look in the
help browser under DiscreteMath or RSolve.  There are many examples.

For example:

In[1]:=
<<DiscreteMath`RSolve`

In[2]:=
RSolve[{a[n+1]==n a[n],a[1]==1},a[n],n]

Out[2]=
{{a[n] -> (1+n)!}}
