WebbThink about it. Consider that you know all the ways to get up with a staircase of n steps, n-1, and so on. Now you have a staircase with n+1 stairs. So: Either your first move is to take 1 step, and then it boils down to a n-steps staircase. Or you take 2 steps and then you have a n-1 staircase. So your recursion formula is Sn+1 = Sn + Sn-1.
