The problem figures below change by a fixed rule. Which option figure continues the series?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
Two things change from figure to figure: the shaded triangle moves one place anticlockwise each time, and the small circle moves one place anticlockwise round the edge of the box each time. So the next figure has the bottom triangle shaded and the small circle at the bottom-right corner.
Why the other options are incorrect
Option (1) — Incorrect. The small circle is right, but the shaded triangle has moved one place clockwise instead of anticlockwise.
Option (2) — Incorrect. The small circle is right, but the shaded triangle has not moved at all since the last figure.
Option (4) — Incorrect. The shaded triangle is right, but the small circle has moved one place clockwise instead of anticlockwise.
