A particular form of generalized Fibonacci sequence is defined, and supplied with the generic name track. Reasons for doing this are discussed, and simple examples of tracks are given. Then an example which occurs in Fibonacci Vector Geometry, namely the vector-product track, is treated in some detail.

A Diophantine m-tuple with the property D(n) is a set { a1, a2 , … am} of positive integers such that for 1 ≤ i < j ≤ m, the number aiaj + n is a perfect square. In the present paper we give necessary conditions that the elements a1 of a set {a1, a2, a3, a4, a5, a6} must satisfy modulo 4 in order to be a Diophantine quintuple.
