Walht - find and continue a pattern - recording results in a table & transfer these results in a graph display

Factory Number	1	2	3	4	5
Number of Grey Squares	2	4	6	8	10
Number of Red Squares	9	15	21	27	33
Number of All Squares	11	19	27	35	43

The blue dots (as represented as the number of the factory) go higher as they require more red & grey tiles to increase in number.

Pattern - Red tile : start with 9 adding  6; Grey tile : start with 2 adding 2.
