The series can be evaluated by plugging in the values of $n$ from 2 to 5 into the formula $3n - 3$. For $n = 2$, the term is $3(2) - 3 = 3$. For $n = 3$, the term is $3(3) - 3 = 6$. For $n = 4$, the term is $3(4) - 3 = 9$. For $n = 5$, the term is $3(5) - 3 = 12$. Adding these terms together gives $3 + 6 + 9 + 12 = 30$.
