Before using the Gizmo, consider an arithmetic sequence with a first term (@) of 4 and a common difference () of 3. A. What are the first five terms of the sequence? B. In the Gizmo, set a1 = 4 and d = 3. The graph in the Gizmo represents the sequence. Click and drag the graph downward to see more points. What are the first five points on this graph? (Place your cursor over any point to see its coordinates.) First five points on the graph: Select the TABLE tab. Each row of this table gives the coordinates of a point on the graph. Check your answers, and then return to the CONTROLS tab. C. The points in the graph of a sequence are called (n, a-) instead of (x, y). For each point, what does n mean? What does a, mean
