Level 3
Some patterns of shaded and unshaded small squares is shown. The unshaded squares are those which lie on the diagonals of the figure. By considering the number patterns,
find the total number of squares in Figure 30,
find the total number of shaded squares in Figure 50.
what will be the figure number that will have 49 squares?
