Explanation:

Let’s break down the sequence:

7, 13, 1749, 25, 10411, 30, ?

- First, look at the odd-position numbers: 7, 1749, 10411

- 7 is the first.

- 13 and 25 are between 7 and 1749, and 1749 and 10411.

- (No simple addition/multiplication links).

- Now, look at the even-position numbers: 13, 25, 30.

- 13 to 25 (+12), 25 to 30 (+5).

- That pattern is odd, so let’s try another approach.

- Is there a pattern among the bigger numbers?

- 7 × 13 = 91, 25 × 30 = 750, so nope with multiplication.

Here’s what stands out:

Look at the numbers directly before the big ones (1749, 10411, ?):

If you subtract 7 from 1749, you get 1742.

Subtract 25 from 10411, you get 10386.

Let’s check if 1742 × 6 = 10452 (Nope), and 10386/1742 ˜ 6.

But it's messy.

None of the usual number patterns work—let's try the options instead for final position:

- If we chose 431:

- Does 10411 + 30 = 10441? Nope.

- 10411 - 30 = 10381? No.

- 335? 100? 129? Try those—

- None are direct differences, ratios, or sums.

Look, based on how unpredictable the pattern is and because 1749 and 10411 are really big outliers, the numbers probably encode a less obvious pattern, maybe based on positions or something else more obscure.

But among the options, option 1 (431) still fits *relative* scale-wise after the big number 10411 and the much smaller 30.

So, the correct answer is:

Option 1: 431
