To find out if a meaningful word can be formed using specific letters from the series, let's first identify these letters based on their position: 'B 8 4 C R M 9 P D K W F A 2 E J 7 X U Q H L T Y 6 G S'.
The letters of interest are:
- Ninth letter: D
- Sixteenth letter: J
- Twenty-fourth letter: Y
- Twenty-seventh letter: S
The selected letters are: D, J, Y, and S.
Next, we determine if these letters can form a meaningful word. Upon reviewing possible combinations:
- There are no standard English words composed of D, J, Y, and S.
Since a meaningful word cannot be formed, the answer is 'X'.
