C Correct answer
Explanation

The pattern alternates: +24, +37, +19, +33, +33. The expected pattern should be +24, +37, +19, +33, +24 (repeating the first difference). 236+33=269, which is correct. The term 203 is wrong because 147 should be followed by 236-33=203, but the difference pattern is broken. 184 is the wrong term.
