- Let's analyze the given series: 30, 42, 56, 72, ?, 110.

- Notice the pattern: each term is separated by an increment that increases by 2.

- Calculate the differences:

- 42 - 30 = 12

- 56 - 42 = 14

- 72 - 56 = 16

- The difference is increasing by 2: 12, 14, 16.

- So, next difference should be 18.

- Add 18 to the last term: 72 + 18 = 90.

- Option 3: 90 is the correct number to replace the question mark.

- 90
