1. In a winter season, let us take the temperature of Ooty from Monday to Friday to be in \(A\).\(P\). The sum of the temperatures from Monday to Wednesday is \(0^\circ C\) and the sum of the temperatures from Wednesday to Friday is \(18^\circ C\). Find the temperature on each of the five days.
 
The temperature of each five days is i°C,i°C,i°C,i°C,i°C.
 
 
2. Two \(A.P\)’s have the same common difference. The first term of one \(A.P\) is \(2\) and that of the other is \(7\). Show that the difference between their \(10^{th}\) terms is the same as the difference between their \(21^{st}\) terms, which is the same as the difference between any two corresponding terms.
 
Difference between their corresponding terms \(=\)
