HINT 

    T1 is the first term of the sequence.


    T2 is the second term of the sequence.


    Sn is the sum of the first "n" terms of the sequence.


        So, S1 is the first term of the sequence; same as T1;  therefore, S1 = T1.


            S2 = T1 + T2.   Therefore,  T2 = S2 - S1.


Happy learning (!)
