Describe the pattern of squares in figures 1-4, and determine the number of squares in figure 4.

Questions 3.2 and 3.3 cannot be answered as the relevant pattern or context is not provided in the image.

Here is the solution for question 4.1:

Step 1: Analyze the visual pattern in Figures 1-4.

• Figure 1 consists of 3 squares.
• Figure 2 consists of a $2 \times 2$ grid of squares with an additional square on top of the top-right square, totaling $2^2 + 1 = 5$ squares.
• Figure 3 consists of a $3 \times 3$ grid of squares with an additional square on top of the top-right square, totaling $3^2 + 1 = 10$ squares.
• Figure 4
