### Abstract

In this paper, we study the existence of entire solutions of finite-order of non-linear difference equations of the form \begin{aligned} f^{n}(z)+q(z)\Delta _{c}f(z)=p_{1}\mathrm{e}^{\alpha _{1}z}+p_{2}\mathrm{e}^{\alpha _{2}z},\quad n\ge 2 \end{aligned} f n ( z ) + q ( z ) Δ c f ( z ) = p 1 e α 1 z + p 2 e α 2 z , n ≥ 2 and \begin{aligned} f^{n}(z)+q(z)\mathrm{e}^{Q(z)}f(z+c)=p_{1}\mathrm{e}^{\lambda z}+p_{2}\mathrm{e}^{-\lambda z},\quad n\ge 3 \end{aligned} f n ( z ) + q ( z ) e Q ( z ) f ( z + c ) = p 1 e λ z + p 2 e - λ z , n ≥ 3 where q, Q are non-zero polynomials, $$c,\lambda ,p_{i},\alpha _{i}(i=1,2)$$ c , λ , p i , α i ( i = 1 , 2 ) are non-zero constants such that $$\alpha _{1}\ne \alpha _{2}$$ α 1 ≠ α 2 and $$\Delta _{c}f(z)=f(z+c)-f(z)\not \equiv 0$$ Δ c f ( z ) = f ( z + c ) - f ( z ) ≢ 0 . Our results are improvements and complements of Wen et al.
