Question

Given that N={1,2,3,….,100} then I. Write the subset A of N whose element are odd number II. Write the subset B of N , whose element are represented by x+2 , where xɛN

Answer 1

Answer:

Solution:

(i) A = {x | x ∈ N and x is odd}

A = {1, 3, 5, 7, …, 99}

(ii) B = {y | y = x + 2, x ∈ N}

1 ∈ N, y = 1 + 2 = 3

2 ∈ N, y = 2 + 2 = 4, and so on.

Therefore, B = {3, 4, 5, 6, … , 100}
