Pete's rule is "Add 2, Multiply by 2." He started with 6 and wrote the numbers below. 6, 8, 16, 18, 36 Is Pete's pattern correct?

No, Pete's pattern is not correct. If we follow his rule starting with 6, we would get:

(6 + 2) x 2 = 16
(16 + 2) x 2 = 36
(36 + 2) x 2 = 76

Therefore, the correct pattern using Pete's rule from 6 would be 6, 16, 36, 76.
