As an alternative to dark energy it has been suggested that we may be at thecenter of an inhomogeneous isotropic universe described by aLemaitre-Tolman-Bondi (LTB) solution of Einstein's field equations. In order totest this hypothesis we calculate the general analytical formula to fifth orderfor the redshift spherical shell mass. Using the same analytical method wewrite the metric in the light-cone by introducing a gauge invariant quantity$G(z)$ which together with the luminosity distance $D_L(z)$ completelydetermine the light-cone geometry of a LTB model.
