Options

- B42 P
- C26 D

Correct answer
C. 26 D
Step-by-step solution
The differences between consecutive numbers are increasing by 2: (5-2)=3,(10-5)=5,(17-10)=7,(26-17)=9 . The next difference should be 9, so Number will be 26. The Alphabet pattern is subtracting 3 positions to the alphabet each time: P (16th), M (13th), J (10th), G (7th), The next letter will be G (7th) - 3=D (4th) So Answer will be 26 D.
