Common ratio means that you will be multiplying from the first number to get the second number.
To find the ratio we will work backwards, from right to left, and divide instead of multiply.
-43/-21.5 = 1/2
-86/-43= 1/2
-182/-86 = 1/2
r = 1/2
3:34...............................
The answer is 5.50$ you have to divide 16.50/ 3
To find your answer do 14+5 which is 19 so your answer is 19
