The third one(-20+(n-1)*)

Step-by-step explanation:

It's correct because when you plug in one of the numbers in the list, it makes the equation equal. Example Below.

n=4

n=-20+(n-1)8

4=-20+(4-1)8

4=-20+3*8

4=-20+24

4=4

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
