## Algebra 1: Common Core (15th Edition)

Answer choice $F$: $a(n)=5+(n−1)(6)$
A function rule is written as $a(n) = a + (n-1)d$. $a$ is the first term, and $d$ is the common difference. The first term is $6$, and the common difference is $5$. Substitute these terms in. $\boxed{a(n) = 5 + (n-1)6}$ The answer is $\boxed{F}$
