Abstract:In this paper, we investigate the generalized (r,s,t,u) sequence and we deal with, in detail, three special cases which we call them (r,s,t,u), Lucas (r,s,t,u) and modified (r,s,t,u) sequences. We present Binet's formulas, generating functions, Simson formulas, and the summation formulas for these sequences. Moreover, we give some identities and matrices related with these sequences.
“…where W 0 ; W 1 ; W 2 are arbitrary complex (or real) numbers and r; s; t are real numbers. This sequence has been studied by many authors, see for example [3] and references therein. The sequence fW n g n 0 can be extended to negative subscripts by de…ning…”
