3 4 5 6 The next number is 1 plus the previous number So the pattern rule is the next number is n + 1
the answer is 72.:)
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)
The pattern alternates between two sequences: one decreasing by 1 (18, 13) and the other decreasing by 2 (4, 6). Following this pattern, the next number after 6 should be 3 (6 - 3), and the next number after 13 should be 12 (13 - 1). Thus, the next two numbers in the sequence are 12 and 3.
