Answer 2

Answer:

6 degrees Celsius

Step-by-step explanation:

The total of all temperatures for the first 4 days is 4 times their mean:

 4 × 1 °C = 4 °C

The total of temperatures for the first 5 days is likewise the number of days times the mean:

 5 × 2 °C = 10 °C

The only thing added to the total of the first 4 days to give the total for 5 days is the temperature on the fifth day is 6 C

4+6=10
