(C) The set of integers `lt 10` (D) The set of factors of 10

State whether the followmg sets are finite or infinite. (i) The set of months in a year. (ii) {1,2,3, ..., 99, 100) (iii) The set of prime numbers smaller than 99. (iv) The set of letters in the English alphabet. (v) The set of lines that can be drawn are parallel to the X-Axis (vi) The set of numbers which are muitiplies of 5. (vii) The set of circles passing through the origin (0,0).

If two integers a and b be such that -2 lt a lt 0 and 0 lt b lt 2 , then show that (i) (a +b) belongs to the set of whole numbers W : (ii) (b-a) belongs to the set of natural numbers N : (iii) (a-b) belongs to the set of integers Z .
