Find the fourth term of the
geometric sequence, given the
first term and common ratio.
a=8 and r=4

The fourth term of the geometric sequence is 512.

Step-by-step explanation:

To find the geometric sequence of the nth term we will use the formula:

An = a×r^(n-1)

As, we have to find the fourth term,

A4 = 8×(4)^4-1

A4 = 8×64

A4 = 512.

why can't you?

step-by-step explanation:

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
