Abstract The purpose of this communication is to define and illustrate the notions of $\mathcal{J}(S_\sigma: \mathcal{G})$-summable, $\mathcal{J}(S_\sigma: \vartheta: \mathcal{G})$-summable and $\mathcal{J}(N_\sigma: \vartheta: \mathcal{G})$-summable sequences
in gradual normed linear spaces (briefly abbreviated as $GNLP$) and to demonstrate some connections between their corresponding sequence spaces.
