Answer:
147,456
Step-by-step explanation:
Geometric sequence: 9, 18, 36
Common ratio = r = 18/9 = 2
First term : a_1 = 9
Nth term : a_n = a_1 * r^(n - 1)
a_n = 9 * (2)^(n -1)
We want a_15, the 15th term
a_15 = 9*2^(15 -1)
a_15 = 9*2^14 = 9*16,384 = 147,456
Answer:
$24
Step-by-step explanation:
original price of a dress = $30
