Answer:
The general formula for the
n
t
h
term in a geometric sequence is this:
T
n
=
a
r
n
−
1
T
8
=
a
r
7
=
60
T
6
=
a
r
5
=
72
, and know we have to solve for
r
, and we can do this by using the two information we have:
T
8
T
6
=
60
72
=
a
r
7
a
r
5
=
r
2
60
72
=
r

6
=
r

As you'll see, we don't need to square root
r
2
:
T
10
=
a
r
