It is difficult to determine the exact rule without more information or a pattern provided. However, upon observation, it appears that both sequences have a mix of numbers and letters. In sequence X, the pattern is as follows:
- Start with X and subtract 1 from each subsequent element: X-1, (X-1)-1, (X-1)-1-1, etc.
- The letter B is the 6th element, so it could be interpreted as (X-1)-1-1-1-1= B.
In sequence Y, the pattern is less clear without more information or context.
X-1, 2, 3, 4, 8, B
Y-3, 12, 27, 48, A,243
