Answer 2

To find the missing number in the sequence, let's examine the given numbers:

12 (56) 16 17 (?) 21

At first glance, it seems that the numbers might be arranged in a pattern. However, without further information or context, it is challenging to determine the exact pattern.

Please provide any additional information or context you may have about the sequence, or let me know if you made any errors while inputting the sequence.
