Here are the patterns and rules for each sequence in Table 3:
Sequence 1:
- Pattern: The sequence consists of squares made of smaller unit squares. The side length of the square increases by one unit in each step.
- Can you draw the next shape? Why or why not? Yes, the next shape can be drawn. The pattern is consistent: the side length of the square increases by 1 unit for each subsequent shape. The next shape would be a 4×4 square.
- Rule or pattern: The n-th shape in the sequence is an n×n square. The number of unit squares in each shape is the square of its position in the sequence, given by n2.
Sequence 2:
- Pattern: The sequence consists of a single triangle, and its orientation alternates.
- Can you draw the next shape? Why or why not? Yes, the next shape can be drawn. The pattern is a clear alternation of the triangle's orientation. The next shape would be a single triangle pointing upwards.
- Rule or pattern: The shape is always a single triangle. Its orientation alternates between pointing upwards and pointing downwards.
Sequence 3:
- Pattern: The sequence consists of a horizontal row of circles. The number of circles in the row increases by one in each step.
- Can you draw the next shape? Why or why not? Yes, the next shape can be drawn. The pattern is consistent: one additional circle is added to the row for each subsequent shape. The next shape would be a row of 5 circles.
- Rule or pattern: The n-th shape in the sequence is a row of n circles. The number of circles in the row is equal to its position in the sequence.
