What comes next? B25, Y2, C24, X3, ?
To solve this logical reasoning sequence, let's analyze the given series: B25, Y2, C24, X3, ?
Step 1: Breaking Down the Series
- B25: The letter is 'B', and the number is 25.
- Y2: The letter is 'Y', and the number is 2.
- C24: The letter is 'C', and the number is 24.
- X3: The letter is 'X', and the number is 3.
Step 2: Analyzing Patterns in Letters
- Observe the pattern in the sequence of letters: B, Y, C, X...
- B and C are consecutive letters in the alphabet (increment of 1), and similarly, Y and X are consecutive in reverse order (decrement of 1).
- The pattern alternates: +1, -1, +1,... Therefore, after C, the next letter should be B+2 (forward movement), meaning D.
Step 3: Analyzing Patterns in Numbers
- The numbers are alternating between decreasing and increasing: 25 down to 2, then 24 down to 3.
- The pattern shows: 25-1=24, 2+1=3,.. implying: 24-1=23.
Step 4: Combining Both Patterns
- According to the patterns determined, the next combination should be: D23.
Conclusion
The correct option that fits the observed pattern is D23.
