    Problem 3. A ternary string is a sequence of O's, 1's and 2's. Just like a bit string, but with three symbols 0,1 and 2. Let's call a ternary string good provided it never contains a 2 followed immediately by a 0, i.e., does not contain the substring 20. Let Go be the number of good strings of length n. For example, G_1=3, and G. = 8 (since of the 9 ternary strings of length 2, only one is not...

    11: I can identify the predicate being used in a proof by mathematical induction and use it to set up a framework of assumptions and conclusions for an induction proof. Below are three statements that can be proven by induction. You do not need to prove these statements! For each one clearly state the predicate involved; state what you would need to prove in the base case; clearly state the induction hypothesis in terms of the language of the proposition...
