Abstract
In this paper, closed forms of the summation formulas for generalized Tetranacci numbers are presented. Then, some previous results are recovered as particular cases of the present results. As special cases, we give summation formulas of Tetranacci, Tetranacci-Lucas, fourth order Pell, fourth order Pell-Lucas, fourth order Jacobsthal, fourth order Jacobsthal-Lucas numbers.
Keywords: Tetranacci numbers, Tetranacci-Lucas numbers, sum formulas, summing formulas.
