sequence, which has dozens of fascinat- eral formula for the n th number in the ing properties. There are many ways to sequence is (1/2) × n × (3 n – 1). The first few generate the Morse-Thue sequence. One way are 1, 5, 12, 22, 35, 51, 70, and 92. Curiously, is to visualize this as a sequence of 0s and 1s. all numbers of such a type end in 0, 1, 2, 5, 6, Start with a zero and then repeatedly do the or 7. This problem can also be solved simply following replacements: 0 → 01 and 1 → 10.
