Question
If  7     43    x     1311  Â
 5247       15739 Then, x - x/2 + 2 = ? 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
7 × 7 - 6 = 43 43 × 6 + 5 = 263 263 × 5 - 4 = 1311 1311 × 4 + 3 = 5247 5247 × 3 - 2 = 15739 Hence, x = 263 Hence, 263 - 263/2 + 2 = 263 - 131.5 + 2 = 263 - 129.5 = 133.5
