Explanation:

Let's look at the series step by step:

- 32

- 30

- 68

- 207

- 832

- 4165

- 24996

Now, let's check patterns:

- 32 to 30: -2

- 30 to 68: +38

- 68 to 207: +139

- 207 to 832: +625

- 832 to 4165: +3333

- 4165 to 24996: +20831

These aren't simple addition/multiplication. Let's look for a multiplication pattern:

If we try multiplying and adding:

32 x 1 - 2 = 30

30 x 2 + 8 = 68

68 x 3 + 3 = 207

207 x 4 + 4 = 832 (207 x 4 = 828)

But 828 + 4 = 832, so this works.

832 x 5 + 5 = 4165 (832 x 5 = 4160; 4160 + 5 = 4165)

4165 x 6 + 6 = 24996 (4165 x 6 = 24990; 24990 + 6 = 24996)

But the first step does not fit.

32 x 1 - 2 = 30 (but shouldn't it be +1 or +0 so first can be in pattern?)

So 30 is not fitting in the multiplication pattern like the others.

The correct answer is:

Option:1, 30 is the wrong number.

- Option 2: 207 - Fits the pattern

- Option 3: 4165 - Fits the pattern

- Option 4: 32 - Start of the series

- Option 5: 68 - Correct by the rule

So, 30 disrupts the multiplication + n pattern.

Conclusion: Option 1 (30) is the wrong number.
