Why the perturbative QTF Theory is an asymptotic theory,because in the asymptotic expansion,the error at N order is a ''infinity small'' of order the (N+1)th term (meaning O(term(N+1)).So I wonder why we know the error at order N in perturbative QTF Theory is of approximation of (N+1)th term in the series.

Thank you very much in advanced.
