Answer 2
Answer:

Answer: Choice A)  -4, -2, 0, 2

Explanation:

This is because we are adding the same thing to each term to get the next term. That is the common difference d = 2

  • second term = (first term)+d = -4+2 = -2
  • third term = (second term)+d = -2+2 = 0
  • fourth term = (third term)+d = 0+2 = 2
