Question

Describe the following sets in Roster form:
$\{\text{x} \in\text{N} :\text{x}=\text{2n, n}\in\text{N}\};$

✓

Answer

In Roster form, we describe a set by listing its elements, separated by commas and the elements are written within braces { }. If a set has infinitely many elements, them comma is followed by ..., where the dots stand for 'and so on'. The above set can be written as {2, 4, 6, 8....} since all those natural numbers, which can be written as a multiple of 2 are the even natural numbers.
