Abstract: We give applications of the quasi-Fibonacci numbers of order 7, the so-called sine-Fibonacci numbers of order 7, and many other new kinds of recurrent sequences to the decompositions of some polynomials. We also present the characteristic equations, generating functions and some properties of all these sequences. Finally, some new Ramanujan-type formulas are generated.
