An arithmetic sequence is given. Find the common difference and write out the first four terms.
-$\{ 3 n + 2 \}$
A) $\mathrm { d } = 2 ; 3,5,8,11$
B) $d = 3 ; 5,8,11,14$
C) $\mathrm { d } = 3 ; 3,5,8,11$
D) $\mathrm { d } = 2 ; 5,8,11,14$

The sequence is defined by $3n + 2$. The common difference $d$ is the coefficient of $n$, which is 3. The first four terms are obtained by substituting $n = 1, 2, 3, 4$ into the expression, resulting in 5, 8, 11, and 14.
