If l,m,n are the pth, qth, rth terms respectively of a G.P.`(l,m,ngt0) then |(logl, p, 1),(logm,1,1),(logn,r,1)|`= (A) `pqr `(B)` l+m+n `(C) 0 (D) none of these

If a,b,c are positive and are the pth, qth and rth terms respectively of a G.P., the the value of |(loga, p, 1),(logb, q, 1),(logc, r, 1)|= (A) 1 (B) pqr(loga+logb+logc) (C) 0 (D) a^pb^qc^r

If a,b,c be the pth, qth and rth terms respectively of a H.P., the |(bc,p,1),(ca,q,1),(ab,r,1)|= (A) 0 (B) 1 (C) -1 (D) none of these

l, m,n are the p^(th), q ^(th) and r ^(th) term of a G.P. all positive, then |{:(logl, p, 1),(log m, q, 1),(log n ,r,1):}| equals :

If a,b,and c are positive and are the pth, qth and rth terms respectively of a GP. Show without expanding that |{:(loga,p,1),(logb,q,1),(logc,r,1):}|=0

If the pth, qth and rth terms of a G.P, are x,y and z repectively, then prove that |{:(logx,p,1),(logy,q,1),(logz,r,1):}|=0

If a,b,c be the pth , qth and rth terms of an A.P., then p(b-c) + q(c-a) + r(a-b) equals to :

If x ,y ,a n dz are pth, qth, and rth terms, respectively, of an A.P. nd also of a G.P., then x^(y-z)y^(z-x)z^(x-y) is equal to a.x y z b. 0 c. 1 d. none of these

If a,b, and c are respectively,the pth,qth, and rth terms of a G.P.,show that (q-r)log a+(r-p)log b+(p-q)log c=0
