If the number `16, 20, 16, d` form a A.G.P. then d can be equal to :

Three integers form an increasing G.P. If the third number is decreased by 16, we get an A.P. If then the second number is decreased by 2, we again get a G.P. The smallest number of the original G.P. is

If a, b, c, d are in G.P., then (a + b + c + d)^(2) is equal to

The numbers 1, 4, 16 can be three terms (not necessarily consecutive) of a.no. A.P b.only one G.P c.infinite number of A.P's d.infinite nuber of G.P' s

The numbers 1, 4, 16 can be three terms (not necessarily consecutive) of no A.P. only on G.P. infinite number o A.P.’s infinite number of G.P.’s

If a, b are the roots of equation x^(2)-3x + p =0 and c, d are the roots of x^(2) - 12x + q = 0 and a, b, c, d are in G.P., then prove that : p : q =1 : 16

Which of the following are A.P.s ? If they form an A.P., find the common difference d and write the next three terms . 2,4,8,16"….."

If the product of three number is G.P.is 512. If 4 is added in first number and second then number will be in A.P.then find the sum of the original numbers (A) 16 (B) 20 (C) 28 (D) 24

The numbers 1,4,16 can be three terms (not necessarily consecutive) of no A.P.only on G.P. infinite number o A.P.s infinite number of G.P.

If the set A contains 5 elements, then the number of elements in the power set P(A) is equal to a)32 b)25 c)16 d)8
