Here are descriptions for how two dot patterns are growing,
• Pattern A Step 2 has 10 dots. It grows by 3 dots at each additional step.
Pattern B: The total number of dots can be expressed by 2n^2+1, where n is the
step number
For each pattern, draw a diagram of Step 0 to Step 3.

The steps in the patterns A and B form a sequence

The attached diagram represents dots in patterns A and B

How to draw the diagrams

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

[tex]T_n =2n^2 + 1[/tex]

When n = 0 to 3, we have:

[tex]T_0 =2(0)^2 + 1 =1[/tex]

Step 0 = 1 dot

[tex]T_1 =2(1)^2 + 1 =3[/tex]

Step 1 = 3 dots

[tex]T_2 =2(2)^2 + 1 =9[/tex]

Step 2 =  9 dots

[tex]T_3 =2(3)^2 + 1 =19[/tex]

Step 3 =  19 dots

Next, we draw the diagrams of both patterns (see attachment)
