question 257

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 \(n \geq 2\)
