Consider the following number series and answer the question based on this.

18, 10, 12, 27, x, p

z + 4 = x - 27

Series I : 14, x, 37, 53, 72

Series II : 48, x, 26, 53, 213, 1705

Series III : 8, 15, x, 35, 48, 63 The value of x is 24.

Explanation:

- Series I: Subtracting the previous number from the current provides a consistent pattern. The numbers show a consistent incremental series. For example, 24 + 13 = 37. The series is satisfied here with x = 24.

- Series II: This is a more complex series that doesn’t adhere consistently with x = 24. The pattern breaks as we progress. So x = 24 doesn’t satisfy this series properly.

- Series III: The pattern involves adding consecutive odd numbers. The sequence fits well with x = 24 here, as 15 + 9 = 24 and 24 + 11 = 35. This series is satisfied.

The correct choice is Option 2: Only II because this is the series where x = 24 doesn't fit well.
