-$a _ { 1 } = 1 , d = 3$
A) $a _ { n } = n + 3$
B) $a _ { n } = 2 n - 3$
C) $a _ { n } = 3 n - 2$
D) $a _ { n } = 3 n + 2$

The general formula for the nth term of an arithmetic sequence is $a_n = a_1 + (n - 1)d$, where $a_1$ is the first term and $d$ is the common difference. Substituting $a_1 = 1$ and $d = 3$ gives $a_n = 1 + (n - 1)3 = 3n - 2$.
