What is the value of the fourth term in a geometric sequence for which a1= 30 and r = 1/2

= 3.75

Step-by-step explanation:

The n th term of a geometric sequence is

= a₁

where a₁ is the first term and r the common ratio

Here a₁ = 30 and r = , thus

= 30 = 30 × = = = 3.75

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
