Let C1 ,C2,........ Cn ... Be a sequence of concentric circles . The nth circle has the radius n and it has n openings. A point P starts traveling on the smallest circle C1, and it leaves it at an opening along the normal at the point of opening to reach the next circle C2.Then it moves on the second circle C2, and leaves it likewise to reach the third circle C3 and so on . Find the total number of different paths in which the point can come out of the nth circle.
