In this manuscript we investigate the existence of the fractional finite difference equation (FFDE) Δ μ ? 2 μ x ( t ) = g ( t + μ ? 1 , x ( t + μ ? 1 ) , Δ x ( t + μ ? 1 ) ) via the boundary condition x ( μ ? 2 ) = 0 and the sum boundary condition x ( μ + b + 1 ) = ∑ k = μ ? 1 α x ( k ) for order 1 < μ ≤ 2 , where g : N μ ? 1 μ + b + 1 × R × R → R , α ∈ N μ ? 1 μ + b , and t ∈ N 0 b + 2 . Along the same lines, we discuss the existence of the solutions for the following FFDE: Δ μ ? 3 μ x ( t ) = g ( t + μ ? 2 , x ( t + μ ? 2 ) ) via the boundary conditions x ( μ ? 3 ) = 0 and x ( μ + b + 1 ) = 0 and the sum boundary condition x ( α ) = ∑ k = γ β x ( k ) for order 2 < μ ≤ 3 , where g : N μ ? 2 μ + b + 1 × R → R , b ∈ N 0 , t ∈ N 0 b + 3 , and α , β , γ ∈ N μ ? 2 μ + b with γ < β < α .
