Write a recursive formula to define the sequence.
-$$a _ { 1 } = 2 , d = - 9$$
A) $a _ { 1 } = 2$ and $a _ { n } = a _ { n - 1 } + 9$ for $n \geq 2$
B) $a _ { 1 } = 2$ and $a _ { n } = a _ { n - 1 } - 9$ for $n \geq 2$
C) $a _ { 1 } = 2$ and $a _ { n } = a _ { n + 1 } - 9$ for $n \geq 2$
D) $a _ { 1 } = 2$ and $a _ { n } = - 9 a _ { n - 1 }$ for $n \geq 2$

The given sequence starts with $a_1 = 2$ and has a common difference $d = -9$, indicating it is an arithmetic sequence where each term is found by subtracting 9 from the previous term. Therefore, the recursive formula is $a_n = a_{n-1} - 9$ for $n \geq 2$.
