Abstract: In Theorem 1 a set of sufficient conditions is investigated for the summability factor of type $ {\theta _n} \in (\vert\bar N ,q{\vert _k},\vert\bar N ,p{\vert _k}),k \geq 1$. In the special case when $ k = 1$ three different sets of necessary and sufficient conditions are established in Theorem 2 for the factor $ {\theta _n}$. Various known and some new results are also deduced as special cases.
