We obtain a result on Ulam stability and on the best Ulam constant for the linear difference equation \(x_{n+3}=ax_{n+2}+bx_{n+1}+c x_n,\)\(a,b,c \in \mathbb {K}\), where \(\mathbb {K}\) is one of the fields \(\mathbb {R}\) or \(\mathbb {C},\) and \((x_n)_{n\ge 0}\) is a sequence in a Banach space X over the field \(\mathbb {K}\).

我们获得乌拉姆稳定性和最佳乌拉姆常数线性差分方程的结果\(X_ {N + 3} = ax_ {N + 2} + bx_ {N + 1} + C x_n,\)\(一, b,c \ in \ mathbb {K} \),其中\(\ mathbb {K} \)是字段\(\ mathbb {R} \)或\(\ mathbb {C},\)和\ ((x_n)_ {n \ ge 0} \)是Banach空间X中字段\(\ mathbb {K} \)上的序列。
