The pattern in the series appears to alternate between adding 3 and multiplying by 3. Starting with 15, we add 3 to get 18, then multiply by 3 to get 54. Next, we add 3 to 54 to get 57, and then multiply by 3 to reach 171. Following this pattern, the next step is to add 3 to 171, which gives us 174. Thus, the next number in the series is 174.

A single number cannot define a sequence, even less a series.
The next number is the sequence 236175969, 48, 12 is 236175861.
The series seems to be "add 3," so the next number in the series would be 12 followed by 15.
