Sum-free sequence

In mathematics, a sum-free sequence is an increasing sequence of positive integers, such that no term can be represented as a sum of any subset of the preceding elements of the same sequence. This differs from a sum-free set, where only pairs of sums must be avoided, but where those sums may come from the whole set rather than just the preceding terms.
