The main result of our work is to prove that that summability by Natarajan's method implies summability by Abel's method in one or two variables. On the other hand, we illustrate some related examples to clarify the validity of our approach. 2023 29 31 1956 https://creativecommons.org/licenses/by/4.0/ 10.54216/GJMSA.060203 https://americaspg.com/journal/33/article/1956 https://americaspg.com/storage/61690398349.pdf
