Pick the figure from the options that best continues the given figure series.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
Two things change from figure to figure: the shaded triangle moves one place clockwise each time, and the black dot moves one corner clockwise each time. So the next figure has the right triangle shaded and the black dot at the bottom-left corner.
Why the other options are incorrect
Option (1) — Incorrect. The shaded triangle is right, but the black dot has moved one corner anticlockwise instead of clockwise.
Option (2) — Incorrect. The shaded triangle is right, but the black dot has not moved at all since the last figure.
Option (3) — Incorrect. The black dot is right, but the shaded triangle has moved one place anticlockwise instead of clockwise.
