Explanation:

Let’s break this down step by step. We’re looking at the series W, Q, ?, H, E, C and have to find what fits where the question mark is. Here’s what’s going on:

- The letters are changing, not randomly, but by skipping backward by a set pattern in the alphabet.

- W to Q is a jump—let’s count: W (23rd), Q (17th). That’s a drop of 6 letters.

- Q to ?: That’s what we need. Let’s see if a pattern emerges if we compare what comes next.

- H is after the mystery letter, E comes after H, and C comes after E.

Checking the skips:

- W (23) to Q (17): -6

- Q (17) to ?

- ? to H (8)

- H (8) to E (5): -3

- E (5) to C (3): -2

Notice, the differences are -6, (?), something, -3, -2. Could the pattern be: -6, -4, -3, -2? Let’s test that.

- W -6 = Q

- Q -4 = 17 - 4 = 13 ? M

- M -3 = 13 - 3 = 10 ? J

- J -2 = 10 - 2 = 8 ? H

But this doesn’t perfectly match the series.

Let’s try comparing just the given sequence.

Check if there’s another pattern. Let’s look at the list backwards:

- C (3), E (5): +2

- E (5), H (8): +3

- H (8), ?: N/A

- ?: Q (17)

- Q (17), W (23): +6

If we reverse the jumps: +2 (from C), +3 (to H), next should be +4 then +6 (reaching Q), then +6 again to W.

From H (8), +4 = 12 (L)

So L goes between Q and H.

Now, looking at your options:

1. N—doesn’t fit the jump

2. L—fits the jump (+4 from H to L)

3. K—wrong jump

4. M—wrong pattern

The answer is: Option 2: L
