Given the recurrence relation a_n = 4a_{n-1} - 4a_{n-2}, with initial conditions a_0 = 2, a_1 = 6, derive the unique sequence.
💡 Hint: Think about how repeated roots modify coefficients and constants in the general solution.
Solve the recurrence relation a_n + a_{n-1} + a_{n-2} = 0 and find its unique sequence given initial conditions 1, -1, -1.
