In this paper, the authors investigate the generalized Ulam-Hyers stability of n− dimensional cubic-quartic functional equation f ( n−1 ∑ b=1 vb + rvn ) + f ( n−1 ∑ b=1 vb− rvn ) = r2 [ f ( n ∑ b=1 vb ) + f ( n−1 ∑ b=1 vb− vn )] −2(r2−1) f ( n−1 ∑ b=1 vb ) + 2(r+1) r [ f (rvn)− r3 f (vn) ] where r is a positive integer with r 6=±0,1 in the setting of intuitionistic fuzzy normed spaces using direct and fixed point methods.
