The pattern behind it: Growing patterns and tables
Find the rule, so Figure 250 is no harder than Figure 4.
In this one. When a list goes up by the same amount every time, you reach any later term by adding that step over and over in a table — you never have to draw the figure itself.
How to spot it
A row of figures or a table of numbers is shown for the first few terms only, and the question asks for a term far further along, such as 'Figure 6' or 'Figure 250'.
Common mistake
Children extend the sequence one term at a time by drawing or counting. Finding the fixed step or relationship lets them jump straight to the term asked for.
