If you have ever tried making patterns with a collection of coins, you have probably noticed that you can make hexagons in a natural way by packing circles as tightly as possible. the figure below shows how 19 circles fit into a hexagonal shape with 3 circles on each edge. let h(n) be the number of circles you need to form a hexagon with n circles on each edge. from the figure below, it is clear that h(2) = 7 and h(3) = 19. it can be shown that increasing the number of circles on each edge gives the following recurrence relation: h(n) = 1 if n = 1 h(n − 1) + 6n − 6 if n > 1. calculate h(9).
