For the given sequence:
15, 14, 13, 12, 11, 10, 9
we can observe a clear pattern: each number is decreasing by 1. As we analyze the sequence step by step:
- 15 – 1 = 14
- 14 – 1 = 13
- 13 – 1 = 12
- 12 – 1 = 11
- 11 – 1 = 10
- 10 – 1 = 9
Continuing this pattern, we can deduce that the next number after 9 should be:
9 – 1 = 8
Thus, the next number in the sequence is 8.
