A strictly increasing sequence of positive integers (a_n) is said to be (weakly) complete if every sufficiently large positive integer is representable as a sum of distinct terms of (a_n). We extend this concept by saying a sequence (a_n) is r-complete if every sufficiently large positive integer is representable as the sum of r or more distinct elements from (a_n). We establish a number of results related to r-complete sequences. In particular, for any positive integer r we construct an example of a sequence which is r-complete but not (r+1)-complete.
