Quite recently, Bor [Quaest. Math. (doi.org/10.2989/16073606.2019.1578836, in
press)] has proved a new result on weighted arithmetic mean summability
factors of non decreasing sequences and application on Fourier series. In
this paper, we establish a general theorem dealing with absolute matrix
summability by using an almost increasing sequence and normal matrices in
place of a positive non-decreasing sequence and weighted mean matrices,
respectively. So, we extend his result to more general cases.
