Write a recursive formula to define the sequence.
-$$a _ { 1 } = 5 , d = 4$$
A) $a _ { 1 } = 5$ and $a _ { n } = a _ { n - 1 } - 4$ for $n \geq 2$
B) $a _ { 1 } = 5$ and $a _ { n } = a _ { n + 1 } + 4$ for $n \geq 2$
C) $a _ { 1 } = 5$ and $a _ { n } = a _ { n - 1 } + 4$ for $n \geq 2$
D) $a _ { 1 } = 5$ and $a _ { n } = 4 a _ { n - 1 }$ for $n \geq 2$

The sequence starts with $a_1 = 5$ and has a common difference $d = 4$, indicating it is an arithmetic sequence where each term is 4 more than the previous term. Therefore, the recursive formula is $a_n = a_{n-1} + 4$ for $n \geq 2$.
