N2 - A cosmological model of an holographic dark energy interacting with dark matter throughout a decaying term of the form Q = 3 (λ1 ρDE + λ2 ρm) H is investigated. General constraint on the parameters of the model are found when accelerated expansion is imposed and we found a phantom scenario, without any reference to a specific equation of state for the dark energy. The behavior of equation of state for dark energy is also discussed.
