Given the question, it appears there is insufficient information or pattern to determine a clear and definitive answer. The problem setup does not provide an obvious method or rule to solve or predict the next number after 1 being 2.
Therefore, with the information provided, it is not possible to determine what comes next. The problem seems to lack sufficient clues or instructions to find a solvable pattern or to follow any explicit mathematical reasoning.
Thus, the question cannot be solved given the current details and context.
