Serial Reasoning Flashcards

A matrix has three rows. Each row's shapes increase in number: row 1 has 1 star, row 2 has 2 stars, row 3 has ___.

Answer: 3 stars

Each row adds one star, so row 3 contains 3 stars.

In a pattern sequence, shapes get lighter in shade each step: black, dark gray, gray, ___. What comes next?

Answer: Light gray

The shading decreases one level per step, making the next shade light gray.

A 3×3 grid contains X, O, and △ in each row, each appearing exactly once. Row 1 is X-O-△, row 2 is O-△-X. What is row 3?

Answer: △-X-O

Each symbol shifts one position left each row in a Latin square pattern, giving △-X-O for row 3.

A serial pattern shows a rectangle, then the same rectangle with a diagonal line, then the rectangle with two diagonal lines. What comes fourth?

Answer: Rectangle with three diagonal lines

One diagonal line is added per step, so the fourth figure has three diagonal lines.

Each row of a matrix has shapes that grow larger left to right: small-medium-large. The pattern in columns is ___.

Answer: The same size appears in each column across all rows

In a consistent size matrix, the same size (e.g., small) appears in the same column across all rows.

A sequence shows: circle inside a square, circle inside a triangle, circle inside a pentagon, ___. What is the missing figure?

Answer: Circle inside a hexagon

The outer shape gains one side each step (4→3→5 is irregular; correcting: square=4, pentagon=5, hexagon=6).

In a 3×3 matrix, each row has one black cell and two white cells. Moving down, the black cell shifts from position 1 to position 2 to position ___.

Answer: Position 3

The black cell moves one position to the right each row, reaching position 3 in the third row.
