Answer:

  (b)  a1 = 6, a(n) = a(n -1) +5

Step-by-step explanation:

It helps to recognize the form of a recursive definition for an arithmetic sequence. It looks like ...

  [tex]a_1=\text{(first term)},\ a_n=a_{n-1}+d\qquad\text{for common difference $d$}[/tex]

Only one of the offered answer choices has this form. That is the correct choice.
