Explanation:

For the number series problems, the numbers can be ascending or descending, added, subtracted, multiplied or divided either by a common number or with incrementing with a particular pattern.

Calculation:

Given series is 4, 3, 6, 25, ?, 1503

Logic is:

1. The preceding number is used to calculate the next number.
2. The second number is odd number and is incremented by 2 for every number forward.
3. The third number is the same as the second number.

The numbers in the series can be written as follows

Initial number to start the series is 4.

3 = 4 * 1 - 1

6 = 3 * 3 - 3

25 = 6 * 5 - 5

X = 25 * 7 - 7 = 168

1503 = 168 * 9 - 9

Therefore the number in the place of ? is 168.

Option D 168 is the correct answer.
