Correct Answer :

Option C

41

24

Solution :

The correct answer is 41.

To find the next number in the series, let us calculate the difference between consecutive terms:

12.5-8=4.5

19.5-12.5=7

29-19.5=9.5

Next, let us analyze the pattern in the differences between consecutive terms:

7-4.5=2.5

9.5-7=2.5

We can see that the difference increases by 2.5 at each step. Thus, the next difference to be added is:

9.5+2.5=12

Adding this value to the last term of the given series:

29+12=41

Therefore, the number that comes next in the series is 41.
