Question

$2$ is a member of the set of first five counting numbers.

Answer 1

Given sentence:

$2$ is a member of the set of first five counting numbers

The symbol '$\in$‘ means ’is a member of' or “belongs to” and the symbol '$\notin$' means “is not a member of” or does not belongs to".

First five counting number is $\left\{1,2,3,4,5\right\}$ and $2$ is a member of this group.

The proper symbol can be written as $2\in$$\left\{1,2,3,4,5\right\}$

Hence, $2\in \left\{1,2,3,4,5\right\}$
