چکیده
In this paper, we establish the Hyers-Ulam-Rassias stability of the following functional equation $$ (4p)^nf\left(\frac{x_1+\cdots +x_{(4p)^n}}{(4p)^n}\right) + 4p\sum_{i=1}^{(4p)^{n-1}} f\left(\frac{x_{4pi-4p+1} + \cdots +x_{4pi}}{4p}\right) = 2 \sum_{i=1}^{(4p)^n} f\left(\frac{x_i+x_{i+1}}{2}\right) $$ in fuzzy Banach spaces.
