Answer 2

15) The set of natural numbers greater than 50 € N,W,I

16) The set of natural numbers less than 15 € I

17) { 21 , 22 , 23 , 24 , .....} € N,W,I

18){10,11,12,.......} € N,W,I

19) {1,3,5,7,...…} € odd numbers,N,W,I

20) {Monday,,....} € days

N = natural numbers

W = whole numbers

I = integers
