The pattern is add three and then multiply by three. The next number is 174.
The next three numbers in the sequence are 23, 25, and 27.
Each number is three times the previous number.
The numbers are halving each time, so the next three are 60, 30 and 15.
11, -10, 9
42 123 243
6, 15, 24, 33, 42, 51, 60
Of course, you can make infinitely many series that start with these numbers. One possibility is that the difference between consecutive numbers inreases 5 at a time (10, 15, 20, etc.).
To find the next number in the series 16, 23, 19, 19, 22, 15, 25, we can look for a pattern among the numbers. The differences between consecutive numbers are +7, -4, 0, +3, -7, +10. The next difference appears to be -6, which would lead to the next number being 25 - 6 = 19. Therefore, the next number in the series is 19.

-3 0 3 then 6 9 12 15 18 21 and so on ...
27, 33, and 39. The pattern adds 6 each time
