Question
If  2,  7, 20,  x ,  110,  235,
Then,  7 x + 7√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
2 ×  2 + 3,  7 × 2 + 6,  20 × 2 + 9,  49 × 2 + 12,  110 × 2 + 15, 235 Hence, x= 49 Hence, 7 x + 7√x = 7 × 49 + 7√49 = 343 + 7 × 7 = 343 + 49 = 392
