Puzzle 4 


We have been quite lucky with the weather recently, it has got steadily warmer each day, over the last five days.

By this, I mean that the temperature rose by the same amount each day.

The average temperature was 2 °C, and I know it froze on two occasions (0 °C).

I also know the product of the temperatures was over 500 but below 2,000 and each temperature was an integer.

What were the last 5 temperatures?
