Topic 4: Visual Patterns Activity 3. For each of the following, (i.) draw the first three terms of a visual pattern that has the given number of blocks in the neh figure. There needs to be a coherent visual pattern; that is, someone should be able to draw the fourth term by looking only at what you drew; (ii.) Explain what each component of the given expression means in your figure. For example, given 2(n- 1) + 1, (i.) my first three terms of a visual pattern that has 2(n - 1) +1 squares in the nob figure look like the following: odd (ii.) The component 2(n - 1) in the nth figure expression comes from adding a set of (n - 1) horizonal squares and a set of (n - 1) vertical squares. The component + 1 represents adding the lower right corner square to the total. Here is a visual explanation with n = 4: a. n2 b. 2n + 1 c. (n + 2)(n) - 1
