Correct option is D
The pattern in the sequence:
3, 10, 24, (...), 108.
Difference between 3 and 10 is 7.
Difference between 10 and 24 is 14.
The next difference is 28 (doubling 14), so 24 + 28 = 52.
Then, 52 to 108 has a difference of 56 (doubling 28).
Thus, the missing number is 52.
So, the correct answer is: (d) 52.
