Hello everybody, Thank you for all your suggestions but all what I need is to sum the coeficients of my K list. I do this: << DiscreteMath`RSolve` K = {a1 + b1 x + c1 x^2 , a2 + b2 x + c2 x^2, a3 + b3 x + c3 x^2}; Sum[SeriesTerm[K[[i + 1]], {x, 0, 0}], {i, 0, 2}] Sum[SeriesTerm[K[[i + 1]], {x, 0, 1}], {i, 0, 2}] Sum[SeriesTerm[K[[i + 1]], {x, 0, 2}], {i, 0, 2} Out[1]= a1 + a2 + a3 Out[2]=b1 + b2 + b3 Out[3]=c1 + c2 + c3 Is there any way to do more simply than that. Because with a very big list the SeriesTerm does not give me the right result. Cheers. Lian.
