The steps in the patterns A and B form a sequence
The attached diagram represents dots in patterns A and B
<h3>How to draw the diagrams</h3>
For pattern A, we have:
Step 2 = 10 dots
Increment of 3 dots in each step
This means that:
Step 0 = 4 dots
Step 1 = 7 dots
Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule
When n = 0 to 3, we have:
Step 0 = 1 dot
Step 1 = 3 dots
Step 2 = 9 dots
Step 3 = 19 dots
Next, we draw the diagrams of both patterns (see attachment)

Answer:
the expected value= $90
Step-by-step explanation:
when sell is $600 an average of 1 in 100 will claim $20,000
and an average 1 in 200 will claim $30,000
and an average of 1 in 500 will claim $550,000.
company sells 20,000 policies
The expected profit loss can be written as
= 600 - (1/100 * 20000) - (1/200 * 30000) - (1/500 * 80000)
= 600 - 200 - 150 - 160
= 90
Therefore, the expected value= $90
