In this paper, we will give some conditions for a numerical semigroup to have maximal or almost maximal length or to be Arf . For obtaining these conditions, we will use the type sequences  and , in cases and ,  where  for , respectively.


Key words: Arf semigroup, numerical semigroup, type sequence, maximal Length.
