(p+qth) term of G.P is m and p-qth term is n its pth term is and qth t

1.	(p+qth) term of G.P is m and p-qth term is n its pth term is and qth term is
Answer» ANSWER: Let the FIRST term of G.P be 'a' and COMMON ration be 'r' given T p+q =ar p+q−1 =m T p−q =ar p−q−1 =n then multiplying the above two equations : mn=a 2 r 2p−2 =(ar p−1 ) 2 ⇒ar p−1 = mn but ar p−1 is the P th term of the G.P hence T p = mn

(p+qth) term of G.P is m and p-qth term is n its pth term is and qth term is

Answer»

Let the FIRST term of G.P be 'a' and COMMON ration be 'r'

given T

p+q

=ar

p+q−1

p−q

=ar

p−q−1

then multiplying the above two equations :

mn=a

2p−2

=(ar

p−1

)

⇒ar

p−1

but ar

p−1

is the P

term of the G.P

hence T
