The next number in the series 5 10 7 14 11 22 19 is?
The sequence alternates between multiplying by 2 and then subtracting 3. Starting with 5, you multiply by 2 to get 10, then subtract 3 to get 7, multiply by 2 to get 14, subtract 3 to get 11, multiply by 2 to get 22, and subtract 3 to get 19. Following this pattern, the next operation is to multiply 19 by 2, resulting in 38. Therefore, the next number in the series is 38.
