I need the correct answer

5.2: Bowling for Triangles (Part 2) Here is a visual pattern of dots. The number of dots D(n) is a function of the step number n. Step 1 Step 2 Step 3 Step 4 1. What values make sense for n in this situation? What values don't make sense for n? 2. Complete the table for Steps 1 to 5. D(n) 2 D(1) + 2 = 3 3 D(2) + 3 =6 4 5 3. Following the pattern in the table, write an equation for D)(n) in terms of the previous step. Be prepared to explain your reasoning. Are you ready for more? Consider the same triangular pattern. 1. Is the sequence defined by the number of dots in each step arithmetic, geometric, or neither? Explain how you know. 2. Can you write an expression for the number of dots in Step " without using the value of " from a previous step
