What is the next number in the series: 8, 14, 9, 15, 10, 16 ...?

To determine the next number in the series, let's analyze the patterns established by the numbers given.

The sequence alternates between two different patterns. The first pattern consists of the numbers: 8, 9, 10, which increments by 1 each time, while the second part consists of the numbers: 14, 15, 16, which increments by 1 as well.

Following the established patterns, after 10 (which is the last number in the first part of the sequence), the next number should follow the increment in the second part, which was 16. Continuing this pattern, the number after 16 would be 17.

Thus, after the number 10, which corresponds to the first part of the alternating series, the subsequent number that follows would logically be 17, indicating that the sequences are connected through their alternating nature.

It's important to note that the number 11, although following 10, does not correspond with the established sequence logic. The next number indeed follows from the second pattern, ensuring continuity across both parts of the series.
