Answer:

Adding 3x each time

Step-by-step explanation:

To find the difference, subtract the 1st value from the 2nd; 2nd value from the 3rd;.........

(6x + 3)=1st value

(9x + 3)=2nd value

(12x + 3)=3rd value

9x+3-(6x+3)

9x+3-6x-3

9x-6x=3x

Check

6x+3+3x

=9x+3

12x+3-(9x+3)

12x+3-9x+3

12x-9x=3x

Check

9x+3+3x

=12x+3
