12,18,15,21,18,?,?,?,?,?,?,

12 + 6 = 18

18 - 3 = 15

15 + 6 = 21

21 - 3 = 18

What do you think the next numbers are?

13,26,18,36,23,?,?,?,

13 * 2 = 26

13 + 5 = 18

18 * 2 = 36

18 + 5 = 23

What do you think the next numbers are?

Can you see a pattern in the next two groups of numbers? If you post your answers, we'll be glad to check them for you.
