In this paper, we introduce the notion of a generalized difference I-convergent (i.e.∆ m-I-convergent) and difference I-Cauchy (i.e.∆ m-I-Cauchy) sequence in intuitionistic fuzzy n-normed spaces. Further, we prove some results related to this notion. Also, we study the concepts of a generalized difference I *-convergent (i.e.∆ m-I *-convergent) sequence in intuitionistic fuzzy n-normed spaces and show the relation between them.
