Abstract
In this paper, closed forms of the sum formulas for generalized Tribonacci numbers are presented. As special cases, we give summation formulas of Tribonacci, Tribonacci-Lucas, Padovan, Perrin, Narayana and some other third-order linear recurrance sequences.
Keywords: Tribonacci numbers, Padovan numbers, Perrin numbers, sum formulas
