Suppose n hive of bees flew No. There fn ways. Obviously, f 1 = 1, f 2 = 2. Will have to fly to No.

Suppose n hive of bees flew No. There fn ways. Obviously, f 1 = 1, f 2 = 2. Will have to fly to No. n will go through helb the first n-1 number or No. n-2. The following diagram, available fn = f n-1 + f n-2 Fibonacci number of columns in the plant kingdom is one of the most amazing performance: some sunflower seeds on seed disc is arranged according to the spiral, namely two logarithmic spiral, a group clockwise, counterclockwise turn a group. The number of spirals of different groups, surprisingly: the number of two spirals often become Fibonacci number series in two successive. Sunflower normal size 34 and 55 spirals, however, there are up to 89 large sunflower and 144, and even a larger 144 and 233 sunflower spiral. Pineapple, Jing Dong, cones, oxeye, and many plants, flowers, and more another pile coincidence: The number of flower petals happens to be a number in the Fibonacci series; engage in electronics may be glad to know specifically designed The circuit can generate a sequence of Fibonacci Fibonacci number.
