Fuzzy Topological Topographic Mapping (F T T M ) is a model for solving neuromagnetic inverse problem. F T T M consists of four components and connected by three algorithms. F T T M version 1 and F T T M version 2 were designed to present 3D view of an unbounded single current and bounded multicurrent sources, respectively. In 2008, Suhana proved the conjecture posed by Liau in 2005 such that if there exist n number of F T T M , then n 4 − n new elements of F T T M will be generated from it. In this paper, a new proof of sequence of F T T M is presented using k-Fibonacci sequence.
