The expressions x-6, 2x, and x^2 from the first three terms of a geometric progression. By calculating two different expressions for the common ratio, form and solve an equation in x to find possible values of the first term.

Question

anonymous · Answer

for a,b,c to be in GP, b^2 = a*c
we can use this to get 'x' from which the first term can be found. hope tht helps

anonymous · Answer

no sorry could you do some of the steps please

anonymous · Answer

did you know the above rule for terms in GP???

anonymous · Answer

what gp? and no

anonymous · Answer

geometric progression :P

for a,b,c to be consecutive terms of a geometric progression,
(a/b)=(b/c) -->(1)
did you know this ???

anonymous · Answer

yes

anonymous · Answer

the same is rewritten by me as b^2 =a*c

anonymous · Answer
