Question

The set - builder form of the set $\{\frac{2}{3},\frac{3}{4},\frac{4}{5},\frac{5}{6},\frac{6}{7}\}$ is

• A. $\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2\le n\le 6\}$
• B. $\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2<n<6\}$
• C. $\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2\le n<6\}$
• D. $\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2<n\le 6\}$

Answer 1

The correct option is A

$\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2\le n\le 6\}$

$\{x:x=\frac{n}{n+1},\text{where}nϵN\text{and}2\le n\le 6\}$
