State Whether each of the following sets is a finite set or an infinite set .

The set of integers less that $10$

The set of whole number less than 12 .

$\left\{x:x=3n-2,n\in W,n\le 8\right\}$

$\left\{x:x=3n-2,n\in Z,n\le 8\right\}$

$\left\{x:x=\frac{n-2}{n-1},n\in w,\right\}$

Answer, whether the following statements are true or false,  give reasons.

The set of even natural numbers less than $21$ and the set of odd natural numbers less than $21$ are equivalent set.

 If E $=\{$ factors of $16\}$ and F  $=\{$ factors of $20\}$ then E $=$ F 

The set A $=\{$ integers less than $20\}$ is a finite Set .

Answer, whether the following statements are true or false,  give reasons .

If A$=\{x:x$ is an even prime number $,\}$ then set A is empty.
