  1. A 3x3 matrix uses three sizes per row and column: small, medium, large. Row 1: large, small, medium. Row 2: small, medium, large. Row 3: ___, large, small.

    Answer: Medium

    Row 3 needs medium (missing from row). Column 1 has large (row 1) and small (row 2), missing medium. Both confirm medium.

  2. A matrix pattern: cells alternate X and O in rows. Row 1: X, O, X. Row 2: O, X, O. Row 3: X, ?, X. What is the missing cell?

    Answer: O

    Row 3 follows the X-O-X alternating pattern. The middle cell of Row 3 is O.

  3. A 3x3 matrix rule: right cell = left cell + middle cell. Row 1: 2, 3, 5. Row 2: 4, 5, 9. Row 3: 6, 7, ___.

    Answer: 13

    Rule: right = left + middle. Row 3: 6 + 7 = 13.

  4. In a matrix, the main diagonal (top-left to bottom-right) contains stars (★). All other cells contain circles (○). What is in Row 2, Column 2?

    Answer: ★

    Row 2, Column 2 is on the main diagonal, so it contains a star (★).

  5. In a pattern matrix, shapes gain one side per column: Column 1 = triangle (3 sides), Column 2 = square (4 sides), Column 3 = pentagon (5 sides). Rows alternate shading: Row 1 = shaded, Row 2 = unshaded, Row 3 = shaded. What is in Row 2, Column 2?

    Answer: Unshaded square

    Column 2 = square. Row 2 = unshaded. Result: unshaded square.

  6. A 3x3 matrix has numbers following the rule: each number = sum of row index and column index. What value appears in Row 2, Column 3?

    Answer: 5

    Row 2 + Column 3 = 2 + 3 = 5.
