What is the recursive rule for the sequence −3, −1, 1, 3...?

= + 2

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 1 - (- 3) = 1 - (- 1) = 3 - 1 = 2

A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is

= + 2

a.)the line for function b is steeper

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
