Explanation:

- Let's check the differences between consecutive numbers in the series.

- The first number is 58, and the second is 179. The difference is: 179 - 58 = 121.

- Next, we go from 179 to the unknown number. With the options provided, we should find a consistent pattern.

- The provided options are 300, 269, 313, and 323. Let's find which continues a pattern.

- After the unknown, the next number is 492. If we select 323: 492 - 323 = 169.

- The differences found so far: 121 (from 58 to 179), and 169 (from the unknown to 492).

- There's an arithmetic progression in the differences. Each jump goes up by 24: 169 - 145 = 24, so use 145 after 121.

- Hence, the unknown number = 179 + 145 = 324.

Therefore:

- Option 4, 323, doesn’t fit the pattern correctly.

- Correct value should be around 324.

. The right number isn't among the options because it should be 324.
