What are the limitations of roster notation?
One of the limitations of roster notation is that we cannot represent a large number of data in roster form. For example, if we want to represent the first 100 or 200 natural numbers in a set B then it is hard for us to represent this much data in a single row. This limitation can be overcome by representing data with the help of a dotted line. Take a set of the first 100 positive odd numbers and represent using roster notation.
What does the dotted line mean in a set?
The dotted line shows that the numbers are part of set B but not written in roster notation. When we represent large numbers of elements in a set using roster form we usually write the first few elements and the last element and we separate these elements with a comma. Let's take a set of all the English alphabets, it can be represented in roster form as:
Why is it not recommendable to use roster notation in set theory?

Can you express all of a set in roster form?
Some sets have infinite elements. It is not actually possible to express all of them in roster form. Similarly, we don’t know the last element in these types of sets.
