Find its first four series of sequence??

Q4. If relation R is transitive then shows that its inverse is also transitive???

Solution:

Suppose that the relation R on A is transitive. Let (a, b) ∈ R-1and (b, c) ∈ R-1. Then by definition of R-1, (b, a) ∈R and (c, b) ∈R. Now R is transitive, therefore if (c, b) ∈R and (b, a) ∈R then (c, a) ∈R. Again by definition of R-1, we have (a, c) ∈ R-1. We have thus shown that for all a, b, c ∈ A, if (a, b) ∈ R1and (b, c) ∈ R-1then (a, c) ∈ R-1. Accordingly R-1 is transitive
