The next two numbers are 26 & 78.
24
36
(6), 12, 18, 24
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
36
54
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.

They are 48, 96 and 192 because the numbers are being doubled after each other
