@rakesh how 4,6,9 will be in gp?

@rakesh why didn't u consider the negative numbers like (-4,-2,-1) they are also in g.p ......plz reply

6 is ans

1 2 4
2 4 8
1 3 9
-1 -2 -4
-2 -4 -8

@HIMA:

In mathematics, a geometric progression (also inaccurately known as a geometric series) is a sequence of numbers such that the quotient of any two successive members of the sequence is a constant called the common ratio of the sequence.

a geometric sequence can be written as:

aq^0=a, aq^1=aq, aq^2, aq^3, ... where q ≠ 0, q is the common ratio and a is a scale factor.

Ex : (4/6) = (6/9) = 2/3.
(9/6) = (6/4) = 3/2.

rakesh is absolutely right

2) 4
For a set of +ve value ,there should be only 2 sets of solutions->
1. if the gp is in the increasing pattern . e.g.- AC

AND ,same things follows for the -ve set of values.
so total no. of diffrent values are: 4

answer is 5
rakesh is right plus if u consider negative value and put in the equation abs(A+B-C) u will
get the same result as before

which is the correct answer??
8 years agoHelpfull: Yes(0) No(0)

three distinct single digit numbers A,B,C are in GP. If abs(x) for real x is the absolute value of x(x if x is +ve or zero, -x if x is -ve), then the number of different possible values of abs(A+B-C) is:
1) 5
2) 4
3) 6
4) 3
