We start with 5 and we count upward. So we simply create a set where x is some number greater than or equal to 5 and we make sure that x is a natural number

So we go from

$A = \{5,6,7,8,\ldots\}$

to

$A = \{x|x\ge5, \ x\in\mathbb{N}\}$

which is the answer

Note: $\mathbb{N}$ is the set of all natural numbers. The set of natural numbers is $\mathbb{N} = \{1,2,3,4,5,6,7,8,\ldots\}$
