abstract = {Let    n be an integer greater than    1. In this paper, we obtained the stability of the multivariable Cauchy-Jensen functional equation     n  f      (        x    1    +      ⋯    +      x    n    ,                    y        1            +              ⋯            +              y        n              n        )    =      ∑          1      ≤      i      ,      j      ≤      n        f  (      x    i    ,      y    j    )in Banach spaces, quasi-Banach spaces, and normed    2-Banach spaces.}
