Answer:
Step-by-step explanation:
The pattern provided is: 12, 15, 10, 13, 8.
To identify the pattern, we can observe the differences between consecutive numbers:
15 - 12 = 3
10 - 15 = -5
13 - 10 = 3
8 - 13 = -5
We can see that the pattern alternates between adding 3 and subtracting 5. Therefore, the next number in the sequence would be obtained by subtracting 5 from the last number given, which is 8:
8 - 5 = 3
So, the next number in the sequence would be 3.
Therefore, the complete pattern would be: 12, 15, 10, 13, 8, 3
