Write each term as a power of 4 and write the next three terms of the sequence 256, 64, 16 , 4

, ,  4²,

continuing the sequence, the next three terms will be

, ,

the sequence is 256, 64, 16, 4, 1, ,

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
