Union of Two Arithmetic Sequences - Basic Calculation Formula (1)

Authors: Waldemar Zieliński
Comments: 8 Pages.

Let A, B denote arithmetic progressions with initial terms equal to 0. The union of A, B is sequence U, containing all elements of A, B without repetitions. We will derive the formula for the n-th element of the union U(A,B)=(u_n) in the form: u_n=f(n,a,b). The continuations of this paper are available in: http://vixra.org/author/waldemar_zielinski
