Abstract

In this chapter, we find the general solution of the following Cauchy–Jensen type functional equation
$$f(\frac{x+y}{n}+z)+f(\frac{y+z}{n}+x)+f(\frac{z+x}{n}+y)=\frac{n+2}{n}[f(x)+f(y)+f(z)],$$
and then investigate the generalized Hyers–Ulam stability of the equation in quasi-β-normed spaces for any fixed nonzero integer n.
