By (A,B), we denote the set of all sequences such that Σ∈ nXn is summable by B whenever ΣXn is summable by A, where A and B are some summability methods. In this paper, we established a simple set of necessary and sufficient conditions for summability factor of type ∈(A,B), and also deduced various known and some new results as special cases. © 2011 Elsevier Ltd.
