2 cards from this section. Quick, good the night before a test.
Define a recurrence equation.
Think about how one term leads to another.
What is A(1) for strings of length 1 without consecutive zeros?
Consider what strings are valid.
What is a recurrence relation?
Think of sequences you know.
True or False: Initial conditions are irrelevant in recurrence equations.
Consider the beginning of a countdown.
Using A(n) = A(n-1) + A(n-2), find A(6), given A(5) and A(4).
You may count on A(5) being a certain value that you previously obtained.
Create your own recurrence relation and solve for the first five terms.
Start small and build up just like adding events on a timeline.
