Let the temperature be initially be t.
Let
be the temperature after day 1 of the period where the teperature decreases.
For example,
is the temperature after the first day
is the temperature after the second day
and so on...
The temperatures during these 10 days are:
The change of the temperature each day, is given by the difference of the temperature in 2 consecutive days, for example day 4 and day 5:
In general, the equation can be given as :
Remark: we cannot see the letters to "drag", so adopt them according to the variables that we defined in the solution.
