None of these

- Let's examine the series: 13, 14, 30, ?, 376, 1885.

- The pattern isn't immediately obvious, so let's look at the differences between numbers.

- From 13 to 14, the difference is 1. From 14 to 30, it's 16.

- From 30 to the unknown number, if it's following the pattern, it's a larger jump.

- From the unknown to 376, we can approximate a large jump as well.

- From 376 to 1885, the increase is 1509.

- Upon closer inspection, each step seems to involve multiplication and addition:

- 13 x 1 + 1 = 14

- 14 x 2 + 2 = 30

- 30 x 3 + 3 = 93

- 93 x 4 + 4 = 376

- 376 x 5 + 5 = 1885

- The correct number is 93, and the pattern is clear.
