I am looking for a way to find an integer that satisfies the statement 5 is divisible by 2^n+1. The answer is 2 and I have tried Solve, Reduce, and FindInstance and not solved the equation.
Solve[Divisible[5,2^n+1]==True,n]
Reduce[Divisible[5,2^n+1]==True,n]
FindInstance[Divisible[5,2^n+1]==True,n]
Solve[Mod[5,2^n+1]==0,n]
Reduce[Mod[5,2^n+1]==0,n]
FindInstance[Mod[5,2^n+1]==0,n]
Is there a way to solve for the answer of 2?
