Question

What is the roster form of N={x|x>2 but x< 10} ?

Answer 1

\(\Large x\in N \) and \(\Large 2<x<10\)

Let \(\Large A =\) {\(\Large x: x\) is a set of even natural numbers between \(\Large 2\) and \(\Large 10\)} .Write this set in roster forms.
\(\Large A =\) {\(\Large x: x\) is a set of even natural numbers between \(\Large 2\) and \(\Large 10\)}.
The roster form of this set can be written as:
\(\Large A =\) {\(\Large 3,4,5,6,7,8,9\)}
