The answer will depend on what the series is! And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
To find the next number in the series, we can observe the alternating pattern between pairs of numbers. The first number is 14, and it decreases by 3 to 11, then increases by 7 to 18. Following this pattern, the next number after 18 should decrease by 2, resulting in 16. Therefore, the next number in the series is 16.

The series is decreasing by consecutive perfect squares starting from 16^2 (256) and decreasing by 2^2 each time. Therefore, the next number in the series would be 4^2, which is 16.
16*3 = 48

Oh, what a happy little sequence we have here! It looks like we're doubling every other number. So, after 16, the next number would be 16 doubled, which is 32. Just like painting a beautiful landscape, sometimes patterns can be found in the most unexpected places.
