What is the next term in this series ?
`B25Y, D23W, F21U`, _______. Options are (a)`I19V` (b) `H19S` (c) `I20T` (d) `H20V`

Options

A. `I19V`
B. `H19S`
C. `I20T`
D. `H20V`

Answer

To find the next term in the series `B25Y, D23W, F21U`, let's analyze the pattern step by step.

### Step 1: Identify the pattern in the letters
The letters in the series are:
- First letters: B, D, F
- Second letters: Y, W, U

**First letters:**
- B (2nd letter of the alphabet)
- D (4th letter of the alphabet)
- F (6th letter of the alphabet)

The first letters increase by 2 each time:
- B → D (+2)
- D → F (+2)

Following this pattern, the next letter should be:
- F (6) + 2 = H (8)

**Hint:** Look for a consistent increment in the letter positions.

### Step 2: Identify the pattern in the numbers
The numbers in the series are:
- 25, 23, 21

The numbers decrease by 2 each time:
- 25 → 23 (-2)
- 23 → 21 (-2)

Following this pattern, the next number should be:
- 21 - 2 = 19

**Hint:** Check for a consistent decrement in the numerical values.

### Step 3: Identify the pattern in the last letters
The last letters in the series are:
- Y, W, U

**Alphabetical positions:**
- Y (25th letter)
- W (23rd letter)
- U (21st letter)

The last letters also decrease by 2 each time:
- Y → W (-2)
- W → U (-2)

Following this pattern, the next letter should be:
- U (21) - 2 = S (19)

**Hint:** Look for a consistent decrement in the alphabetical positions of the letters.

### Step 4: Combine the results
Now we combine the results from the three steps:
- First letter: H
- Number: 19
- Last letter: S

Thus, the next term in the series is **H19S**.

### Final Answer:
The next term is **H19S** (Option B).
