    A simple reasoning engine that solves a specific problem with limited reasoning sophistication.

    If so, it returns the next integer after the second number. Otherwise, it returns None.

This code snippet defines a `ReasoningEngine` class that can solve the problem of determining if two integers are sequential and finding the next integer after them. The class includes methods to check for sequentiality and find the next number, along with an example usage demonstrating its functionality.
