The series alternates between two patterns: one where numbers are multiplied by 3 and then reduced (18 to 27 to 36) and another where numbers are multiplied by 4 and then reduced (81 to 72 to 63). Following this pattern, the next number after 36 (from the first sequence) would be 45 (36 multiplied by 1.25), and after 63 (from the second sequence), the next number would be 54 (63 reduced by 9). Thus, the next number in the series is 45.
The next cube number, after 43 = 64 is 53 = 125.

To find the next number in the sequence 12, 15, 27, 27, 42, we can look for a pattern in the differences between the numbers. The differences are 3, 12, 0, and 15, respectively. The pattern in the differences suggests an increase, so the next difference could be 3 more than the last difference (15), which is 18. Adding 18 to the last number (42) gives us 60. Thus, the next number in the sequence is 60.
18+x=27 calculate and your answer should be 9.

Possibly: 45-54
36
6 12 9 18 15 30 27 54 51
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
Next number= 27 X 3 = 81.
125
27= 3364=43125=53so next number will be 63 = 216
60.75
The next cube number, after 43 = 64 is 53 = 125.
The next number is 49+8 = 57
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
