I would like to solve a recurrence relation of the form

   h[n] == p[n]*h[n + 1] + q[n]*h[n - 1] + (1 - p[n] - q[n])*h[n]
  ,h[1] == 0.5
 }, h[n], n]

where Nn is some boundary condition. This runs and produces a solution, but it doesn't understands that the Nn is the upper bound for n, how can I supply this constraint?

    $\begingroup$ What difference does it make if Nn is upper or not upper if Mma gives answer for all values of n? $\endgroup$

  • $\begingroup$ I can swap 'Nn' in when I see n in the answer indeed, but perhaps a neater formula would be spit out with fixing the boundary $\endgroup$
