We study the asymptotic properties of solutions to nonautonomous dierence equationsof the form\delta^m x_n = a_n f ( n, x_{\sima(n)} ) + b_n,\quad f :\mathbb{N} \times \mathbb{R} \to \mathbb{R} ,\quad \sigma \mathbb{N} \to \mathbb{N}.Using the iterated remainder operator and asymptotic dierence pairs we establish some results concerning approximative solutions and approximations of solutions. Our approachallows us to control the degree of approximation.
