Expert Answer
Relation R in the set N of natural no. R={(x,y):y=x+5 and x<4}
In Roster Form R = {(1,6),(2,7),(3,8)}
Now clearly R is not reflexive since none of the ordered pairs (1,1),(2,2),....etc are inR
Similarly (1,6) is in R but (6,1) is not so it is not symmetric.But it is transitive since there are no ordered pairs of the form
(a,b), (b,c) in R for that (a,c) is not in R .
There are no ordered pairs in R which voilets the definition
So R istransitive.
