Step-by-step solution for: Engaging Math: Visual Pattern Cards
- The top-left panel displays a sequence of three figures. Each figure is composed of yellow squares arranged in a cross-like pattern. The first figure has 5 squares, the second has 9, and the third has 13.
- The top-right panel shows a sequence of three figures, each made of yellow squares. The first figure is a 2x2 square with an extra square on the bottom right, totaling 5 squares. The second is a 3x3 square with an extra square on the bottom right, totaling 10 squares. The third is a 4x4 square with an extra square on the bottom right, totaling 17 squares.
- The middle-left panel presents a sequence of three figures. The first is a single square. The second is a 2x2 square missing one corner, totaling 3 squares. The third is a 3x3 square missing one corner, totaling 8 squares.
- The middle-right panel shows a sequence of three figures. The first is a horizontal row of 3 squares. The second is a 2x2 square with an extra square on the bottom right, totaling 5 squares. The third is a 3x3 square with an extra square on the bottom right, totaling 10 squares.
- The bottom-left panel displays a sequence of three figures. The first is a plus sign made of 5 squares. The second is a larger plus sign made of 9 squares. The third is an even larger plus sign made of 13 squares.
- The bottom-right panel shows a sequence of three figures. The first is a 2x2 square with an extra square on the top right, totaling 5 squares. The second is a 3x3 square with an extra square on the top right, totaling 10 squares. The third is a 4x4 square with an extra square on the top right, totaling 17 squares.
The pattern in the top-left panel is that each subsequent figure adds 4 squares to the previous one (5, 9, 13). This is an arithmetic sequence with a common difference of 4.
The pattern in the top-right panel is that the nth figure is an n+1 by n+1 square with one additional square, so the number of squares is (n+1)^2 + 1. For n=1,2,3, this gives 5, 10, 17.
The pattern in the middle-left panel is that the nth figure is an n by n square with one square missing from a corner, so the number of squares is n^2 - 1. For n=1,2,3, this gives 0, 3, 8. However, the first figure is a single square, which does not fit this pattern. It seems there might be an error in the interpretation or the figure itself.
The pattern in the middle-right panel is that the nth figure is an n by n square with one additional square, so the number of squares is n^2 + 1. For n=1,2,3, this gives 2, 5, 10. But the first figure has 3 squares, which does not fit this pattern.
The pattern in the bottom-left panel is the same as the top-left panel: each subsequent figure adds 4 squares (5, 9, 13).
The pattern in the bottom-right panel is the same as the top-right panel: the nth figure is an n+1 by n+1 square with one additional square, so the number of squares is (n+1)^2 + 1. For n=1,2,3, this gives 5, 10, 17.
Given the inconsistencies in the middle-left and middle-right panels, it is likely that the intended patterns are those in the top-left, top-right, bottom-left, and bottom-right panels, which are consistent and follow clear mathematical sequences. The middle-left and middle-right panels may have been misdrawn or misinterpreted.
Therefore, the correct answer is:
- Top-left: Arithmetic sequence with common difference 4.
- Top-right: (n+1)^2 + 1 squares for the nth figure.
- Bottom-left: Arithmetic sequence with common difference 4.
- Bottom-right: (n+1)^2 + 1 squares for the nth figure.
