%0 Journal Article %T On the Periods of Some Figurate Numbers %A Omur Deveci %A Erdal Karaduman %J Sel£¿uk Journal of Applied Mathematics %D 2011 %I Sel?uk University %X The number which can be represented by a regular geometrical arrangement of equally spaced point is defined as figurate number. Each of polygonal, centered polygonal and pyramidal numbers is a class of the series of figurate numbers. In this paper, we obtain the periods of polygonal, centered polygonal and pyramidal numbers by reducing each element of these numbers modulo m. %K Period %K polygonal number %K centered polygonal number %K pyramidal number. %U http://www.sumam.selcuk.edu.tr/12-2-7.html
