Category:Sixth-order recurrence

After six initial terms ${\displaystyle a_{0}\,}$, ${\displaystyle a_{1}\,}$, ${\displaystyle a_{2}\,}$, ${\displaystyle a_{3}\,}$, ${\displaystyle a_{4}\,}$ and ${\displaystyle a_{5}\,}$, subsequent terms ${\displaystyle a_{n}\,}$ are defined in terms of a formula involving ${\displaystyle a_{n-6}\,}$,

and possibly also ${\displaystyle a_{n-1}\,}$, ${\displaystyle a_{n-2}\,}$, ${\displaystyle a_{n-3}\,}$, ${\displaystyle a_{n-4}\,}$, ${\displaystyle a_{n-5}\,}$ and/or ${\displaystyle n\,}$.
