x 15 is one possibility
27, 33, and 39. The pattern adds 6 each time
To find the next number in the series 12, 5, 11, 21, we can look at the pattern of differences between the numbers. The differences are: -7 (12 to 5), +6 (5 to 11), and +10 (11 to 21). Continuing this pattern, we can assume the next difference will be +6 (to alternate between decreasing and increasing). Therefore, the next number would be 21 + 6 = 27.
The next number in this sequence should be 33.
Each number is decreasing by 3. The next numbers in the sequence would be -18, -21, -24, -27, -30.

21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33

23, 25, 27
It is: 34
-21
Each number is decreasing by 3. The next numbers in the sequence would be -18, -21, -24, -27, -30.
27= 3364=43125=53so next number will be 63 = 216
Either 7, 2 or 27?

21 over 27 is the same as 21 divided by 27:21/27 = 21 ÷ 27 = 0.777778
