Abstract: Here we work out a combinational operator Wn,r(f,x) with zeros of the polynomial through the method of combination average. Convergence order of the operator Wn,r(f,x) is the best if Cj[-1,1](0≤j≤r, r, where r is an arbitrary odd natural number).
Key words: Lagrange interpolation polynomial, pointwise approximation order, linear combination, operator
