In each of the question 1 to 2 a letter series is given with one term missing shown by question mark (?). This term is one four alternative given under it. Find the right alternative.
KLE, IND, GPC , ? , CTA.

Options

A. DRB
B. BSE
C. ERB
D. ECR

Answer

To find the missing term in the series KLE, IND, GPC, ?, CTA, we will analyze the pattern of the letters in each term.

### Step-by-Step Solution:

1. **Identify the Structure of Each Term**:
Each term consists of three letters. Let's denote them as:
- First letter
- Second letter
- Third letter

So, we have:
- KLE
- IND
- GPC
- ?
- CTA

2. **Analyze the First Letters**:
- K (11th letter) → I (9th letter) → G (7th letter) → ? → C (3rd letter)
- The pattern here is that each letter decreases by 2:
- K to I: -2
- I to G: -2
- G to E: -2 (we will find this next)
- E to C: -2

Therefore, the first letter of the missing term should be **E**.

3. **Analyze the Second Letters**:
- L (12th letter) → N (14th letter) → P (16th letter) → ? → T (20th letter)
- The pattern here is that each letter increases by 2:
- L to N: +2
- N to P: +2
- P to R: +2 (we will find this next)
- R to T: +2

Therefore, the second letter of the missing term should be **R**.

4. **Analyze the Third Letters**:
- E (5th letter) → D (4th letter) → C (3rd letter) → ? → A (1st letter)
- The pattern here is that each letter decreases by 1:
- E to D: -1
- D to C: -1
- C to B: -1 (we will find this next)
- B to A: -1

Therefore, the third letter of the missing term should be **B**.

5. **Combine the Letters**:
Now we can combine the letters we found:
- First letter: E
- Second letter: R
- Third letter: B

Thus, the missing term is **ERB**.

6. **Final Answer**:
The missing term in the series is **ERB**.
