16, 12, 8 17. 14, 11 op = -4,-3

3, 7, 15 24, 16. 12 op 4,4 because difference = op 4, 8 = 4 op -8, -4 = 4

Step-by-step explanation:

9+ 2 = 11, 13,15 ordered pair 2

5+ 3 = 8, 11, 14 ordered pair 3

20-4 = 16, 12, 8 ordered pair -4

20-3 = 17. 14, 11 ordered pair -3

1 x 2 +1 = 3, 7, 15 ordered pair 4, 8 = 4
