Which of the following proposed recursive definitions of a function on Z+ produce well-defined functions? If it is well-defined, provide a direct formula for F(n). Be sure to explain your answer, either why F is not well-defined, or why your direct formula is correct. (a) F(n) = 1 + F(bn/2c), for n ≥ 1, F(1) = 1 (b) F(n) = 2F(n−2) if n ≥ 3, F(2) = 1, F(1) = 0 (c) F(n) = 1 + F(n/2) if n is even and n ≥ 2, F(n) = F(3n−1) if n is odd and n ≥ 3, F(1) = 1.

1. Write 3n + 1 Sequence String Generator function (1 point) In lab5.py complete the function sequence that takes one parameter: n, which is the initial value of a sequence of integers. The 3n + 1 sequence starts with an integer, n in this case, wherein each successive integer of the sequence is calculated based on these rules: 1. If the current value of n is odd, then the next number in the sequence is three times the current number...
