question 45

Multiple Choice

Write the first five terms of the sequence defined recursively.Use the pattern to write the nth term of the sequence as a function of n.(Assume that n begins with 1. ) $$a _ { 1 } = 7 , a _ { k + 1 } = a _ { k } - 1$$

• A) \(a _ { n } = 8 - n ; 7,6,5,4,3\) ​
• B) \(a _ { n } = 7 ; 7,7,7,7,7\) ​
• C) \(a _ { n } = 9 - n ; 6,5,4,3,2\) ​
• D) \(a _ { n } = 8 n ; 7,21,28,35,42\) ​
• E) \(a _ { n } = 7 ( n - 1 ) ; 7,14,21,28,35\) ​
