Question
If 4   x  Â
  4           7          15        38.5 Then,  ( x + 1) ( x - 1) = ? In each of the following questions a number series is given. One term of the series is denoted by 'x' . You have to calculate the value of 'x' and by using the value of 'x' , you have to replace the question mark (?) in the following questions :Solution
4 × 0.5 + 1 = 3 3×1 + 1 = 4 4 × 1.5 + 1 = 7 7× 2 + 1 = 15 15×2.5 + 1 = 38.5 Hence, x= 3 Hence, (3 + 1) (3 - 1) = 4 × 2 = 8
