a) Find a recurrence relation that would determine the number of sequences a1, a2, , an
that have an odd number of zeros when each a, E { 0, 1, 2 }, in terms of the number of sequences of
n-1 of these elements that do.
For example when n= 3 we would have the sequences 000, 001, 002, 010, 011, 012, 020, 021, 022,
100, 101, 102, 110, 111, 112, 120, 121, 122, 200, 201, 202, 210, 211, 212, 220, 221, 222.
These sequences consist of all of the base 3 numbers that can be made using 3 digits.
If we let T(n) = # of these sequences with an odd number of O's, we would get for n=3 that T(3) = 12
