Solve the recurrence relation:
For any statements p,q and r, prove that
such that a is even and a +b is even, then b is even."
One student gave an indirect proof as follows:
“Let b be m +1, which is an odd number. We already know a and a +b are even. If we substitute b + m +1 in a + b, it becomes a + m +1, which is an odd number. This contradicts the given statement. Hence b is an even number.”
What is wrong with the above proof ? Also give a correct direct and an indirect proof.
