The next is 3.
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.

The next is 3.
Each following number in the sequence is being divided by 4. Therefore, the next number in the sequence is 3/4 = 0.75.

12The next number in the sequence is the previous # divided by 3. So, 324/3 = 108; 108/3 = 36; 36/3 = 12

If the last number is 1/3 (it should be), the next number is 5 and 1/3
