Unformatted text preview: 11. Let the numbers S n be the determinants dened in Problem 4.3.31. (a) For any n > 2 prove that S n = 3 S n-1-S n-2 . (b) For any k let F k denote the k th Fibonacci number (recall that the Fibonacci sequence 1 , 1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 , 55 , 89 , 144 , . . . is dened by F k = F k-1 + F k-2 ). Prove that F 2 n +2 = 3 F 2 n-F 2 n-2 . (c) Show that S n = F 2 n +2 for each n . 12. ( Bonus Problem ) Problem 3.5.12. Youll need to read Section 3.5 to do this problem. 1...
