### Solution:
Given:
- \alpha = 0.2
- S_1 = 26
### Calculations for Weeks 2 to 10:
#### Week 2:
S_2 = 0.2 \cdot 23 + 0.8 \cdot 26 = 25.4
#### Week 3:
S_3 = 0.2 \cdot 24 + 0.8 \cdot 25.4 = 25.12
#### Week 4:
S_4 = 0.2 \cdot 24 + 0.8 \cdot 25.12 = 24.90
#### Week 5:
S_5 = 0.2 \cdot 23 + 0.8 \cdot 24.90 = 25.12
#### Week 6:
S_6 = 0.2 \cdot 22 + 0.8 \cdot 25.12 = 25.30
#### Week 7:
S_7 = 0.2 \cdot 23 + 0.8 \cdot 25.30 = 25.44
#### Week 8:
S_8 = 0.2 \cdot 22 + 0.8 \cdot 25.44 = 24.55
#### Week 9:
S_9 = 0.2 \cdot 20 + 0.8 \cdot 24.55 = 23.84
#### Week 10:
S_{10} = 0.2 \cdot 20 + 0.8 \cdot 23.84 = 24.27
### Answer:
The forecasted demand for Week 11 using exponential smoothing with alpha = 0.2 is approximately \boxed{24.27}
