Given an infinite sequence of positive integers \cA, we prove that for every nonnegative integer k the number of solutions of the equation n=a1+...+ak, a1, ..., ak∈ \cA, is not constant for n large enough. This result is a corollary of our main theorem, which partially answers a question of Sárközy and Sós on representation functions for multilinear forms. Additionally, we obtain an Erdős-Fuchs type result for a wide variety of representation functions.
