We present some methods for finding asymptotics of some classes of nonlinear higher-order difference equations. Among others, we confirm a conjecture posed by S. Stević (2005). Monotonous solutions of the equation yn=A+(ynk/j=1mβjynqj)p, n0, where p,A(0,), k,m, qj,j{1,,m}, are natural numbers such that q1<q2<<qm,βj(0,+), j{1,,m}, j=1mβj=1, and ys,ys+1,,y1(0,), where s=max{k,qm}, are found. A new inclusion theorem is proved. Also, some open problems and conjectures are posed.
