Question

$4x+1\ge 17$, where $x\in N$

• A. $\{5,6,7,...\}$
• B. $\{4,5,6,...\}$
• C. $\{1,2,3,...\}$
• D. None of these
  

Answer 1

Answer: (B)

$\{4,5,6,...\}$

Given, $4x+1\ge 17$

$\Rightarrow 4x\ge 16$

$\Rightarrow x\ge 4$

Since $x$ is a set of natural numbers.

Therefore, $x=\{4,5,6,7,\mathrm{8....}\}$
