To find the average of the first seven multiples of 8, we first identify those multiples:

1. $8 \times 1 = 8$
2. $8 \times 2 = 16$
3. $8 \times 3 = 24$
4. $8 \times 4 = 32$
5. $8 \times 5 = 40$
6. $8 \times 6 = 48$
7. $8 \times 7 = 56$

Next, we sum these multiples:

$8 + 16 + 24 + 32 + 40 + 48 + 56 = 224$

To find the average, we divide the sum by the number of multiples:

$\text{Average} = \frac{224}{7} = 32$

Thus, the average of the first seven multiples of 8 is 32.
