The next is 3.
The pattern alternates between two sequences. The first sequence is multiplying by 2 (3 to 6, then 6 to 12), while the second sequence adds 1 and then multiplies by 5 (4 to 20). Following this pattern, after 20, the next term in the first sequence would be 12 multiplied by 2, which is 24. Therefore, the next number in the pattern is 24.

No, the sequence 3, 6, 12, 24 is not an arithmetic sequence. In an arithmetic sequence, the difference between consecutive terms is constant. Here, the differences are 3 (6-3), 6 (12-6), and 12 (24-12), which are not the same. This sequence is actually a geometric sequence, as each term is multiplied by 2 to get the next term.

The next number in the sequence is 48.
To find the next number in the sequence 5, 15, 12, 24, 21, 21, 18, we can analyze the pattern. The differences between the numbers are: 10, -3, 12, -3, 0, -3. Following this pattern, the next difference would likely be 12, resulting in a next number of 18 + 12 = 30. Thus, the next number in the sequence is 30.
