Then, a relation among the numbers corresponding to a vertex is given. Furthermore, we obtain a formula which gives the mth term of the sequence formed at the kth vertex in an n-gon. The same procedure is repeated with Pell-Lucas, Jacobsthal and Jacobsthal-Lucas numbers. © 2021 Elsevier Ltd</dc:description><dc:publisher>Elsevier Ltd</dc:publisher><dc:date>2021</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/13359</dc:identifier><dc:identifier>https://doi.org/10.1016/j.chaos.2021.111173</dc:identifier><dc:identifier>0960-0779</dc:identifier><dc:language>en</dc:language><dc:relation>Chaos, Solitons and Fractals</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13359</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
