Multiple Choice

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 $n \geq 2$
