Find the arithmetic mean; 6 and 18, 7 and 27

To find the arithmetic mean of two pairs of numbers, we calculate the average of each pair separately.

1. **First pair: 6 and 18**
   \[
   \text{Mean} = \frac{6 + 18}{2} = \frac{24}{2} = 12
   \]

2. **Second pair: 7 and 27**
   \[
   \text{Mean} = \frac{7 + 27}{2} = \frac{34}{2} = 17
   \]

So, the arithmetic means are:

- For 6 and 18: **12**
- For 7 and 27: **17**
