Answer: 4(a + b + 2)
Step-by-step explanation: 2(2a + b) 8 equals 4a + 2b + 8. 4(a + b + 2) equals 4a + 4b + 8
The value of the 5th term of the geometric sequence is of 160.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:

In which
is the first term.
We already have the 4th term and the common ratio, hence the 5th term is given by:
80 x 2 = 160.
The value of the 5th term of the geometric sequence is of 160.
