noticing a pattern in numbers.

Explanation:

Deductive reasoning starts with general principles and moves to specific conclusions. The statement "All squares are rectangles. ABCD is a square. Therefore, ABCD is a rectangle" follows this pattern, starting from the general fact about squares and rectangles and applying it to the specific square ABCD. The other options are examples of inductive reasoning (generalizing from specific observations like the sun rising daily, students passing a test, or noticing a pattern).

Answer:

All squares are rectangles. ABCD is a square. Therefore, ABCD is a rectangle.
