if `(m+1)th, (n+1)th and (r+1)th` term of an AP are in GP.and m, n and r in HP. . find the ratio of first term of A.P to its common difference

In ( m+1) th, ( n + 1) th, ( r + 1) th terms of an A.P. are in G.P. and m,n,r are in H.P., then ratio of the first term of the A.P. to its common difference interms of n is :

If the (m+1)t h ,(n+1)t h ,a n d(r+1)t h terms of an A.P., are in G.P. and m ,n ,r are in H.P., then find the value of the ratio of the common difference to the first term of the A.P.

If the (m + 1)th, (n + 1)th and (r + 1)th terms of an A.P. are in G.P. and (1)/(m), (1)/(n), (1)/(r ) are in A.P., then find the ratio of the first term of the A.P. to its common difference in terms of n.

If (m+1)^th , (n+1)^th and (r+1)^th terms in AP are in GP m,n,r are in HP ,show that the ratio of the common difference to the first term of the AP is (-2/n).

The 1 st,4 th and 13 th terms of AP are in G.P. The first term is 3. Find the A.P.

If m^(th) n^(th) and o^(th) term of an A.P. are n, o and m. Find common difference d.

The first term of an A.P. is 5 and its common difference is -3 . Find the 11th term of an A.P.

IF m^(th) term of an A.P. is n and n^(th) term is m, then find p^(th) term?

The p^(th), q^(th) and r^(th) terms of an A.P. are in geometric progression then common ratio for G.P is…….
