This sequence does not follow a clear mathematical pattern, making it difficult to determine the next number with certainty. However, one possible interpretation could be that each number is the result of a specific mathematical operation on the previous numbers. For example, if we consider the sequence as the sum of the previous two numbers multiplied by the position of the number in the sequence (e.g., (1+2)*2 = 6, (2+4)*3 = 18), then the next number could be (4+14)*4 = 72.
