Question : Directions: Which number from among the given options can replace the question mark (?) in the following series? 83, ?, 92, 107, 101, 116
Option 1: 81
Option 2: 89
Option 3: 91
Option 4: 98
Correct Answer: 98
Solution : Given: 83, ?, 92, 107, 101, 116
Add 9 to each term to obtain the next alternate term of the series. 83 + 9 = 92; {(?) + 9 = 107 ⇒ (?) = 107 – 9 = 98}; 92 + 9 = 101; 107
Question : If $x+\frac{1}{x}=-2$, then what is the value of $x^{17}+x^{-17}+x^{12}+x^{-12} ?(x<0)$
Option 1: –2
Option 2: –1
Option 3: 1
Option 4: 0
Correct Answer: 0
Solution : Given $x+\frac{1}{x}=-2$ $⇒x^2+1=-2x$ $⇒x^2+2x+1=0$ $⇒(x+1)^2=0$ $⇒x=-1$ Now, putting the value of $x=-1$ in $x^{17}+x^{-17}+x^{12}+x^{-12}$ we get: $=(-1)^{17}+(-1)^{-17}+(-1)^{12}+(-1)^{-12}$ $=-1-1+1+1=0$ Hence, the correct answer is 0.

Option 1: 2
Option 2: 4
Option 3: 6
Option 4: 8
Correct Answer: 2
