Correct Option is 3: 72

- Let's analyze the pattern of the series: 3, 6, 18, ?, 630, 6930.

- Start with 3, multiplied by 2 gives 6.

- Multiply 6 by 3 to get 18.

- Each subsequent number is multiplied by an incremented integer.

- The pattern continues as 18 multiplied by 4, which gives 72, completes the sequence.

- Answers:

- Option 1: 60 - Doesn't fit the multiplication series.

- Option 2: 75 - Incorrect according to the pattern.

- Option 3: 90 - Not fitting the multiplication rule.

- Option 4: 105 - Not satisfying the condition.

- Option 5: 250 - Way off the pattern.

- The missing number follows as 18 × 4 = 72.

The correct number is 72.
