A Random Fibonacci Sequence is a set of numbers that follows a pattern. This pattern involves taking the sum of the two numbers before it. The pattern looks like this: 0, 1, 1, 2, 3, 5, 8, 13, 21... In this pattern, you start with 0 and 1 and then keep adding the two numbers before it. So, to get the next number, you add 0 + 1 to get 1. Then, to get the next number, you add 1 + 1 to get 2. This continues on and on.
