Answer

To find the next number in the pattern 60, 30, 15, we can observe the relationship between the numbers. Let's break it down step by step:

### Step-by-Step Solution:

1. **Identify the Pattern**:
- The first number is 60.
- The second number is 30.
- The third number is 15.

2. **Find the Relationship**:
- To get from 60 to 30, we divide 60 by 2:
\[ 60 \div 2 = 30 \]
- To get from 30 to 15, we again divide 30 by 2:
\[ 30 \div 2 = 15 \]

3. **Apply the Same Operation**:
- Now, to find the next number in the pattern, we will divide 15 by 2:
\[ 15 \div 2 = \frac{15}{2} \]
- This can also be expressed as 7.5.

4. **Conclusion**:
- Therefore, the next number in the pattern is:
\[ \frac{15}{2} \text{ or } 7.5 \]

### Final Answer:
The next number in the pattern is \( \frac{15}{2} \) or 7.5.
