In an AP if Tp=q and Tq=p. Find Tp+q. |
|
Answer» T(p)=a+(p−1)d=qT(q)=a+(q−1)d=p Subtracting 1st equation from the 2nd. d(p−q)=q−p d=−1 Now we will substitute d in the first equation a+(p−1).(−1)=q a=p+q−1 Now we will use the values of a and d in the equation stated below T(p+q)=a+(p+q−1)d =p+q−1+(p+q−1).(−1) =0 ans |
