Directions (Q3-7): What should come in the place of the question mark ...
To find the missing number in the given number series, we need to observe the pattern and analyze the difference between consecutive numbers.

Pattern analysis:
- The given series is decreasing with each subsequent number.
- The difference between consecutive numbers is decreasing as well.
- The difference between 144 and 104 is 40, between 104 and 68 is 36, between 68 and 42 is 26, between 42 and 25 is 17.

Based on the pattern, let's analyze the difference between 25 and the missing number:

- The difference between 42 and 25 is 17.
- The next difference should be less than 17.
- By observing the pattern, we can see that the difference decreases by 4 each time.

Calculation:
- The difference between 42 and 25 is 17.
- The next difference will be 17 - 4 = 13.
- Therefore, the missing number will be 25 - 13 = 12.

So the missing number in the given number series is 12.

Conclusion:
The missing number in the number series 144, 104, 68, 42, 25, ? is 12. Hence, the correct answer is option A) 14.5.
