If x, y and z are the pth, qth, and rth, terms of a G.P respectively, then show that `x^(q-r)` . `y^(r-p)` . `z^(p-q)` = 1.

If pth, qth and rth terms of an A.P. are l, m, n respectively, show that (q-r)l+(r-p)m+(p-q)n=0

If p ^(th), q ^(th) and r ^(th) terms of a G. P. are x,y,z respectively. Find the value of X ^( q-r). Y^( r - p). Z^(p-q)

If the (m + n)th and (m - n)th term of a G.P. are p and q respectively, then the mth term is …….. .

If p, q, r, s are in G.P. then show that (q -r )^(2) + ( r -p) ^(2) + ( s-q) ^(2) = ( p -s) ^(2)

If p to (qvvr) is false, then the truth values of p,q, and r are, respectively.

Select and write the correct answer from the given alternatives in each of the following:If T_p,T_q,T_r are pth,qth and rth terms of an A.P then |(T_p,T_q,T_r),(p,q,r),(1,1,1)| =
