Here, we want to get the set of even numbers between 31 and 75
Even numbers are numbers that are divisible by 2
The first even number after 31 is 32
We proceed to increment this by 2 till we get to 75
Thus, we have the set as:
[tex]\begin{gathered} \text{ \textbraceleft32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62} \\ 64,66,68,70,72,74\rbrace \end{gathered}[/tex]
