A number sequence may be formed by counting the number of dots used to draw each of a set of geometric figures. The first three figures are shown below. (a) (b) (c) (d) Figure 1 Figure Draw Figure 4, the next figure in the sequence above. Complete the table below by inserting the missing information at the rows numbered (i) and (ii). 2 3 4 5 Figure 2 6 Total Number of Dots Formula 5x2-5 5x3-5 Figure 3 5x4-5 Not Required Which figure in the sequence contains 145 dots? Number (n) 5 10 15 Not Required Write an expression in f'for the number (n) of dots used in drawing the fih figure.
