If ` [ [a + 1, a + 2, a + p],[ a + 2, a + 3, a + q],[ a + 3, a + 4, a + r] ] = 0` , then p , q , r are in : [ (1) A P (2) GP (3) H P (4) none

If | (a+1,a+2, a+p), (a+2, a+3,a+q), (a+3,a+4,a+r)|=0,then p ,q ,r are in:

If the numbers p,q,r are in A.P. then m^(7p), m^(7q), m^(7r)(mgt0) are in (A) A.P. (B) G.P. (C) H.P. (D) none of these

suppose x1,x2 are the roots of the equation ax^2+bx+c=0 and x3 and x4 are the roots of the equation px^2+qx+r=0 If a, b, c are in G.P. as well as x_1, x_2, x_3, x_4 are in G.P., then p, q, r are in (i) A.P (ii)G.P (iii)H.P (iv)A.G.P

(3q + 7 p^(2) - 2r^(3) + 4) - (4 p^(2) - 2q + 7r^(3) - 3) = ?

If p:q=3:4 and q:r=8:9 then p:r is

If a_(1),a_(2),a_(3),…. are in A.P., then a_(p),a_(q),q_(r) are in A.P. if p,q,r are in

If p:q=2:3 and q:r=4,:5, then find p:q:r.
