Question

Identify the type of set

$B=\{x:xϵW,x=2n\}$

• A. Finite Set
• B. Null Set
• C. Infinite Set
• D. Singleton Set

Answer 1

The correct option is C Infinite Set

We have to identify the type of set.
Given $B=\{x|x\in W,x=2n\}$ where $W$ represents a set of whole numbers.
$=\{0,2,4,6,8,....\}$ which has infinite number of elements. So it is an infinite set.
Therefore $B$ is an infinite set.
