Step-by-step explanation:
<u>Geometric Sequence</u>
In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
We are given the sequence:
48, 72, 108, ...
The common ratio is found by dividing the second term by the first term:

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.
Now we are sure this is a geometric sequence, we use the general term formula:

Where a1=48 and r=1.5

For example, to find the 5th term:

PQ = 40 inches
The answer is C
The answer is C. X^2-6x+9
12 cm, use the pythagorean theorem: a^2+b^2=c^2
9^2+b^2=15^2
81+b^2=225
b^2=144
b=12
