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.

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?

My 10, 8, 3 is a boisterous lad.
My 9, 4, 8, 7 is the underground part of a tree.
My 6, 5, 7 is admired by some.
My 3, 4, 1, 7 can be used to keep a door shut.
My 2, 1, 7, 6, 9 is where we pray.
My whole is where some discoveries are made.
