Given Q3 = 12 and as = 48. find the explicit rule for the geometric
sequence, given that the common ratio is positive.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

the answer is 9 because the question is telling how much it be together.
