Sorry don't no

Answer 2

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO DETERMINE

The roster form of the set

$\sf{N = \{ \: x : \: x \: is \: odd \: number \: , \: 21 < x < 35, x\in \N \: \} }$

CONCEPT TO BE IMPLEMENTED

SET : A set is a well defined collection of distinct objects

REPRESENTATION OF SET :

A set can be represented in following three ways :

(i) Statement form

(ii) Roster or Tabular form

(iii) Rule or Set builder

EVALUATION

Here the set of Natural numbers is given by

$\sf{ \N = \{1,2,3,4, 5,....... \}}$

Now

$\sf{N = \{ \: x : \: x \: is \: odd \: number \: , \: 21 < x < 35, x\in \N \: \} }$

Since x is a odd natural number between 21 and 35

$\sf{So \: \: \: x = 23, 25, 27, 29, 31, 33}$

Hence The roster form of the set

$\sf{N = \{ \: x : \: x \: is \: odd \: number \: , \: 21 < x < 35, x\in \N \: \} } \: \: is$

$\sf{N \: = \{ \: 23, 25, 27, 29, 31, 33 \: \}\: }$
