Correct Answer :

Option A

156

Solution :

The correct answer is 156.

To find the missing term in the sequence, let us calculate the differences between consecutive terms:

72-35=37

113-72=41

Notice that the differences between consecutive terms are prime numbers in increasing order starting from 37:

37, 41, 43, 47, 53, 59

Following this pattern, the difference between 113 and the missing term (?) must be the next prime number after 41, which is 43:

113+43=156

We can verify the subsequent terms using the next prime numbers:

156+47=203

203+53=256

256+59=315

Therefore, the missing term that replaces the question mark (?) is 156.
