Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The series follows three patterns: first numbers are 2, 7, 14, 23, 34, 47 (differences 5, 7, 9, 11, 13 - consecutive odd numbers). Letters decrease by 1 (Z→Y→X→W→V→U). Last numbers increase by 2 (5, 7, 9, 11, 13, 15). Only 47U15 satisfies all.
