Correct Answer: 112

Solution : To solve this problem, we first need to calculate the values of $x$ and $y$.
$x=\frac{1}{2+\sqrt{3}}×\frac{2-\sqrt{3}}{2-\sqrt{3}}=\frac{2-\sqrt{3}}{1}$
$y=\frac{1}{2-\sqrt{3}}×\frac{2+\sqrt{3}}{2+\sqrt{3}}=\frac{2+\sqrt{3}}{1}$
Now, $x+y =4$............(I)
Also, $xy=(2-\sqrt{3})\times (2+\sqrt{3}) =1$.............(II)
Squaring both sides of equation (I)
⇒ $x^2+y^2+2xy=16$
⇒ $x^2+y^2+2\times1=16$
⇒ $x^2+y^2=14$
Putting the value of $x^2+y^2$ and $xy$ in $8xy(x^{2}+y^{2})$,

Correct Answer: 96

Solution : Given:
16, 32, ?, 192, 576, 1152

Multiply the previous term by 2 and 3 alternately to get the next term.
16 × 2 = 32; 32 × 3 = 96; 96 × 2 = 192; 192 × 3 = 576; 576 × 2 =
