Write the First Five Terms of the Sequence Defined Recursively $a _ { 1 } = 7 , a _ { k + 1 } = a _ { k } - 1$

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) $a _ { n } = 7 ( n - 1 ) ; 7,14,21,28,35$
