I need help find a function for the following recurrence relation
h =2*h +2*h
It's getting to big and messy for me to recognize any pattern.
This is a linear constant coefficient homogeneous difference equation. You treat it like a linear constant coefficient homogeneous ODE.
Take trial solution , substitute this into the recurrence to get a quadratic equation for . Solve the quadratic to get two basic solutions, form a general solution as a linear combination of these two solutions.
