- The series follows a pattern of alternating additions. Let's find it out step by step.

- Start with 357. Add 15 to get 372.

- Add 30 to 372 to find the missing number. 372 + 30 equals 402.

- Add 45 to 402 to get the next number, 447.

- Then, add 60 to 447 and you get 507.

- Now, check the options. Option 3 is 402.

- Hence, the correct number to fit into the series is 402.

Correct Answer: Option 3 - 402
