WebJan 3, 2015 · Prove that: 6 n − 5 n + 4 is divisible by 5 for n ≥ 1 Using Modular arithmetic. Please do not refer to other SE questions, there was one already posted but it was using induction, I want to use this number theory method. Obviously we have to take ( mod 5) So: 6 n − 5 n + 4 ≡ x ( mod 5) All we need to do prove is prove x = 0 How do we do that? WebProof: Suppose that . Then by definition of congruence.

In this case, we may want to think of a as being equal to b. But that would not be right, because a and b are (probably) two different things.
