? 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
2.5× 1 + 1 = 3.5 3.5 × 2 + 2 = 9 9× 3 + 3 = 30 30×4 + 4 = 124 124×5 + 5 = 625 Hence, x= 9 Hence, x2 -1-2x= 92-1 - 2×9 = 81 - 1 – 18 = 62
