Q4. Suppose that A is the set of positive integers. R = {(a,b) | |2a-b| = 1} is a relation on A. Find at least five elements of R. Then draw the graphical representation of R. Draw at least five arrows in that diagram. Q5. Proof by induction: If n 1, then 7-3n is divisible by 4. (Divisible by 4 means, if you divide by 4, then it will be a whole number, not a fraction.)
