Letter series is easy to learn - You will enjoy it.

Letter series classified in three types:

- One lettered series
- Two lettered series
- Three lettered series

In **One lettered series** each term contains one letter and follows a certain pattern.

We have to find out the next term according to that pattern.

```
Example: What is the next letter in the series B, F, J, N, _______ ?
```

1) R

2) T

3) Q

4) S

**Answer:**1) R

**Explanation:**

B = 2, F = 6, J = 10, N = 14 . Here the difference between the letter is 4. So the answer is 14 + 4 = 18 which is R.

```
Example: What is the next letter in the series B, C, E, G, ______ ?
```

1) J

2) I

3) K

4) M

**Answer:**3) K

**Explanation:**

B = 2, C = 3, E = 5, G = 7 . Here the letters are consecutive primes. So the next prime number is 11 which is K.

In **Two lettered series** each term contains two letter and follows a certain pattern.We have to find out the next term according to that pattern.

```
Example: What is the next letter in the series CM, DN, EO, FP, _______ ?
```

1) GR

2) GQ

3) HQ

4) HR

**Answer:**2) GQ

**Explanation:**

C = 3, D = 4, E = 5, F = 6 .

M = 13, N = 14, O = 15, P = 16 .

So next term is G = 7 and Q = 17 .

In **Three lettered series** each term contains three letter and follows a certain pattern.We have to find out the next term according to that pattern.

```
Example: What is the next letter in the series CNL, BLI, AJF, ZHC, _______ ?
```

1) XDY

2) YFZ

3) YFA

4) XFY

**Answer:** 2) YFZ

**Explanation:**

C = 3, B = 2, A = 1, Z = 26 . ( Decreasing by 1 ) So next letter is 25, which is Y.

N = 14, L = 12, J = 10, H = 8 . ( Decreasing by 2 ) So next letter is 6, which is F.

L = 12, I = 9, F = 6, C = 3 . ( Decreasing by 3 ) So next letter is 26, which is Z.
