39. The rule here is starting with the number 9, add (-6 + sequence number * 6).
9 + (-6) = 3
3 + 0 = 3
3 + 6 = 9
9 + 12 = 21
21 + 18 = 39
39 + 24 = 63
The next number in the sequence 3-15-6-30-21 is -207.
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.

If the last number is 1/3 (it should be), the next number is 5 and 1/3
The next number in the sequence 3-15-6-30-21 is -207.

The pattern in the sequence 0, 3, 9, 21 involves adding consecutive odd numbers. Starting with 0, then adding 1+2, 3+6, and 9+12 gives you the next number in the sequence. Therefore, the next number would be 21 + 15 = 36.
35
22
The pattern in the sequence 3, 6, 12, 21 can be identified by examining the differences between consecutive terms: 6-3=3, 12-6=6, and 21-12=9. The differences (3, 6, 9) are increasing by 3 each time. Continuing this pattern, the next difference would be 12 (9 + 3). Therefore, the next number in the sequence is 21 + 12, which equals 33.
This is a Fibonacci sequence. Each number in the sequence is the sum of the previous two numbers:3+5=85+8=138+13=2113+21=34
