We prove that, for certain indices of 6, there are functions whose Cesaro means of order 5 of the Fourier expansion with respect to the polynomials associated with the measure (1 - χ)α(l + χ)β + MAr, where At is the delta function at a point t, are divergent almost everywhere on [-1,1]. We follow Meaney's paper (2003), where divergent Cesaro and Riesz means of Jacobi expansions were proved. .
