Made by AI and not reviewed by a real person.
Look at two shapes sitting side by side. Which pair appears once now, but will appear twice when the empty box is filled to keep the pattern going?
- circle then square
- triangle then circle
- triangle then square
- square then circle
- circle then triangle
Show a hint
- Watch pairs of neighboring shapes as you move along the row, not just one shape at a time.
- Find the pair that appears only once so far. Will filling the box make that pair again?
Show the answer and solution
Answer: D — square then circle
The shapes repeat circle, triangle, square, so a circle goes in the box. Square then circle appears once in the shown row and once more beside the box. Circle then triangle may be tempting, but that pair already appears twice before the box is filled.
