Category:Seventh-order recurrence

After seven initial terms ${\displaystyle a_{0}\,}$, ${\displaystyle a_{1}\,}$, ${\displaystyle a_{2}\,}$, ${\displaystyle a_{3}\,}$, ${\displaystyle a_{4}\,}$, ${\displaystyle a_{5}\,}$ and ${\displaystyle a_{6}\,}$, subsequent terms ${\displaystyle a_{n}\,}$ are defined in terms of a formula involving ${\displaystyle a_{n-7}\,}$,

and possibly also ${\displaystyle a_{n-1}\,}$, ${\displaystyle a_{n-2}\,}$, ${\displaystyle a_{n-3}\,}$, ${\displaystyle a_{n-4}\,}$, ${\displaystyle a_{n-5}\,}$, ${\displaystyle a_{n-6}\,}$ and/or ${\displaystyle n\,}$.
