Answer 2

Answer:

F = {x : x = n², x ∈ N}

Step-by-step explanation:

You can see that every number is a square of natural numbers going to infinity. Hence, x = n² and as every number in this series is a natural number, x ∈ N. and as this series is going to infinity there is no need to say x < something.

Everything in one line is :

F = {x : x = n², x ∈ N}
