This sequence appears to be a repeated pattern of: multiply by 3, divide by 2, multiply by 2
4 * 3 = 12
12 / 2 = 6
6 * 2 = 12
Now repeat the pattern...
12 * 3 = 36
36 / 2 = 18
18 * 2 = 26
Now repeat the pattern to get new terms
36 * 3 = 108
108 / 2 = 54
54 * 3 = 162
136
The next two numbers are 26 & 78.
The next number in the series 4, 12, 6, 12, 36, 18, 36
The next number in the series 4-12-6-12-36-18-36.. is 108.
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
