Answer 2

Answer:

1.) 3

Step-by-step explanation:

A={x/x=n. 2<n<4, x=N}

So, here N means the set of natural numbers. Natural numbers start from 1 and goes till infinity (unending). Then, they are saying 2<n<4 means natural number(s) more than 2 and less than 4. So, it is 3 as it comes between 2 and 4 and is a natural number.
