Question
If  2  4  6  x  14  28  30 Then, x³+ 2
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
2(× 2), 4(+2), 6 (× 2), 12 (+2),  14 (× 2),  28 (+2),  30 Hence, x= 12 Hence, x³+ 2 x  +1 = (12)³+ 2 × 12 + 1 = 1,728 + 24 + 1 = 1,753
