For a set A, let P(A) be the set of all finite subset sums of A. We prove that if a sequence B={b1<b2<⋯} of integers satisfies b1≥11,b2≥3b1+5,b3≥3b2+3 and bn+1>3bn−bn−2(n≥3), then there exists a sequence of positive integers A={a1<a2<⋯} such that P(A)=N∖B. These lower bounds are optimal in a sense. We pose a problem for further research.
