Category:Tribonacci Sequences

This category contains results about Tribonacci Sequences.
Definitions specific to this category can be found in Definitions/Tribonacci Sequences.

The Tribonacci sequence is a sequence $\left \langle {u_n}\right \rangle$ which is formally defined recursively as:

$u_n = \begin{cases} 0 & : n = 0 \\

0 & : n = 1 \\ 1 & : n = 2 \\ u_{n - 1} + u_{n - 2} + u_{n - 3} & : n > 2 \end{cases}$
