What number will replace the question?

Row 1

  • Left = 4
  • Right = 3
    4 − 1 = 3

Row 2

  • Left = 9
  • Right = 12
     9 + 3 = 12

Row 3

  • Left = 12
  • Right = 11
    ⇒ 12 − 1 = 11

So the pattern is alternating:

  • Row 1: −1
  • Row 2: +3
  • Row 3: −1
  • Row 4: +3 (continues)

Apply the Rule to the Last Row
