Correct Answer :

Option D

28

Solution :

The correct answer is 28.

To find the next number replacing the question mark (?), let us analyze the pattern of differences between consecutive terms in the given sequence: 4, 7, 12, 19, ?

Let us calculate the difference between each pair of adjacent numbers:

7-4=3
12-7=5
19-12=7

Notice that the differences between consecutive terms are consecutive odd numbers: 3, 5, and 7.

Following this logical pattern, the next difference must be the next consecutive odd number, which is 9.

To find the missing term (?), add 9 to the previous term (19):

19+9=28

Therefore, the next number in the sequence is 28.
