1. The problem asks for the median temperature of 7 consecutive days with temperatures: 20°C, 22°C, 20°C, 24°C, 21°C, 26°C, and 23°C. 2. The median is the middle value in an ordered list of numbers. For an odd number of values, the median is the value at position $\frac{n+1}{2}$ where $n$ is the number of values. 3. First, order the temperatures from least to greatest: $$20, 20, 21, 22, 23, 24, 26$$ 4. Since there are 7 values, the median is the value at position $\frac{7+1}{2} = 4$. 5. The 4th value in the ordered list is $22$. 6. Therefore, the median temperature is $22^\circ C$. Final answer: C 22°C
