Best answer
Correct Answer - Option 5 : 3584

The pattern of the original number series is

⇒ 15 × 8 = 120

⇒ 120 × 8 = 960

⇒ 960 × 8 = 7680

⇒ 7680 × 8 = 61440

⇒ 61440 × 8 = 491520

According the pattern of the above series the number series starting from the given number 7 would be as:

⇒ A = 7 × 8 = 56

⇒ B = 56 × 8 = 448

⇒ C = 448 × 8 = 3584

 The required number in place of C would be 3584.
