Question
Write the next term of the $\text{AP}\sqrt{8},\sqrt{18},\sqrt{32},....$
✓
Answer
The given AP is $\sqrt{8},\sqrt{18},\sqrt{32},....$
On simplifying the terms, we get :
$2\sqrt{2},3\sqrt{2},4\sqrt{2},....$
Here, $\text{a}=2\sqrt{2}$ and $\text{d}=(3\sqrt{2}-2\sqrt{2})=\sqrt{2}$
$\therefore$ Next term, $\text{T}_4=\text{a}+3\text{d}=2\sqrt{2}+3\sqrt{2}=5\sqrt{2}=\sqrt{50}$
