If the pth, qth and rth terms of an A. P. are in G.P., prove that the common ratio of the G.P. is
`(q-r)/(p-q)`.

If the pth, qth, and rth terms of an A.P. are in G.P., then the common ratio of the G.P. is a. (p r)/(q^2) b. r/p c. (q+r)/(p+q) d. (q-r)/(p-q)

If the pth ,qth and rth terms of an AP are in G.P then the common ration of the GP is

If the 2nd , 5th and 9th terms of a non-constant A.P. are in G.P., then the common ratio of this G.P. is :

The pth, (2p)th and (4p)th terms of an AP, are in GP, then find the common ratio of GP.

If second third and sixth terms of an A.P. are consecutive terms o a G.P. write the common ratio of the G.P.

If second, third and sixth terms of an A.P. are consecutive terms of a G.P. write the common ratio of the G.P.

If the pth, qth, rth, and sth terms of an A.P. are in G.P., then p-q ,q-r ,r-s are in a. A.P. b. G.P. c. H.P. d. none of these

If the pth, qth, rth, and sth terms of an A.P. are in G.P., t hen p-q ,q-r ,r-s are in a. A.P. b. G.P. c. H.P. d. none of these

If pth,qth and rth terms of an A.P. are a, b, c respectively, then show that (i) a(q-r)+b(r-p)+c(p-q)=0

If pth, qth , rth and sth terms of an AP are in GP then show that (p-q), (q-r), (r-s) are also in GP
