Then you have shown that $(a,c+1)$ is an element of $A$ since it satisfies the required condition. That's all you need to show $B$ is a subset.

comment How to handle big powers on big numbers e.g. $n^{915937897123891}$
By the way, your original code computes $n^{2^{915937897123891}}$.

comment What is the relation between the average rate of change and the derivative?
Sorry, your original question only added that restriction at a later point. Hopefully my edit helps to clarify why this does not work.
