- This series is a sequence of numbers where each number represents a pattern based on position.

- Look at the differences between the consecutive numbers: 12 - 6 = 6, 20 - 12 = 8, 30 - 20 = 10.

- Notice that the differences series is increasing by 2. Hence, the next difference should be 12.

- Add this difference to the last number in the series: 30 + 12 = 42.

- Option 1: 42 is the correct choice.

- Option 2: 25 does not fit the pattern.

- Option 3: 49 is not correct based on the differences.

- Option 4: 36 doesn't align with the pattern either.
