Question
If   314     306      x    Â
 269       394    178    1480 Then, 1/3 x + 2x - x = ? 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
314 -2³ = 306,  306 +3³ = 333, 333 -4³ = 269, 269 +5³ = 394, 394 - 6³ = 178 Hence, x = 333 Hence, 1/3× 333 + ( 2× 333) –333 = 111 + 666 - 333 = 444
