Final answer:
There is not enough information or clear pattern to determine the next probable 5-digit number in the sequences provided.
Step-by-step explanation:
The question asks to determine the next probable 5-digit number in a series. Based on the information provided, there does not seem to be a clear pattern or sequence that can be derived to solve for the next number in each of the sequences a, b, and c. The sequences provided do not match any of the reference numbers given in the extra information. Without a discernible pattern or correlation, it is not possible to confidently predict the next number in the sequences. However, if there were other patterns or additional information given, it might be possible to analyze those sequences and provide an answer.
