" Let "a_(1),a_(2),...a_(10)" be a G.P.If "(a_(3))/(a_(1))=25," then "(a_(9))/(a_(5))" equals: "

Let a_(1),a_(2),a_(3),?a_(10) are in G.P.if (a_(3))/(a_(1))=25 then (a_(9))/(a_(5)) is equal to (A)5^(4)(B)4.5^(4)(C)4.5^(3)(D)5^(3)

A geometric sequence has four positive terms a_(1),a_(2),a_(3),a_(4). If (a_(3))/(a_(1))=9 and a_(1)+a_(2)=(4)/(3) then a_(4) equals

Given a_(1),a_(2),......,a_(12) are in G.P. If a_(4)*a_(9)=2019 then value of (a_(2)a_(11)+a_(3)a_(10)+a_(5)a_(8)+a_(6)a_(7))/(a_(4)a_(9)) is equal to

Let a_(1),a_(2),a_(3)... be in A.P.and a_(p),a_(q),a_(r) be in G.P.then value of (a_(q))/(a_(p)) is

Let a_(1), a_(2), a_(3) ….. be terms of an A.P. If (a_(1) + a_(2) + …..a_(p))/(a_(1) + a_(2) + …..a_(q)) = (p^(2))/(q^(2)) (p ne q) then (a_(6))/(a_(21))=

Let a_(1),a_(2),a_(3),...a_(n),......... be in A.P.If a_(3)+a_(7)+a_(11)+a_(15)=72, then the sum of itsfirst 17 terms is equal to:
