Consider the ‘Gibonacci’ numbers Gk defined through the recurrence relation Gk+2 =1/2Gk+1 + 1/2Gk, with G0 = 0 and G1 = 1. This two-term recurrence relation can be converted into a one-term recurrence relation as provided (image), and if we define the column vector uk = (Gk+1, Gk)T, we have uk+1 = Auk, where A is a 2 × 2 matrix. Find the matrix A, and show that uk = Aku0. What is u0?

Consider the ‘Gibonacci’ numbers Gk defined through the recurrence relation Gk+2 =1/2Gk+1 + 1/2Gk, with G0 = 0 and G1 = 1. This two-term recurrence relation can be converted into a one-term recurrence relation as provided (image), and if we define the column vector uk = (Gk+1, Gk)T, we have uk+1 = Auk, where A is a 2 × 2 matrix.

Find the matrix A, and show that uk = Aku0. What is u0?
