8, 12, 18, 27
this is NOT an arithmetic sequence.
It is a geometric sequence and the r value is 3/2.
.
What is the 5th term of this sequence?
27 * 3/2 = 40.5
.
What is the nth term of this sequence?
an = a1*r^(n-1)
where
an is the value of the nth term
a1 is the value of the first term
r is 3/2
n is the number of the term desired
