Weakly Complete Sequence

A Sequence of numbers $V=\{\nu_n\}$ is said to be weakly complete if every Positive Integer $n$ beyond a certain point $N$ is the sum of some Subsequence of $V$ (Honsberger 1985). Dropping two terms from the Fibonacci Numbers produces a Sequence which is not even weakly complete. However, the Sequence

F_n'\equiv F_n-(-1)^n

is weakly complete, even with any finite subsequence deleted (Graham 1964).
