For each affine difference equation and initial condition, find the solution equation.

a) p(n) = 2.5p(n-1)+900; p(0)= 400 - p(0) is the initial condition

b) p(n) = 0.75p(n-1) - 45; p(0) = 510

c) p(n) = 1.03p(n-1) - 75; p(0) = 75

Maybe it's just me, but i have no idea where to start. I have looked at examples in the first few pages of the chapter, only to be led to the wrong answer! Can anyone help??
