Missing Figure
1. The problem is to identify the missing figure in a sequence of squares with small circles positioned differently inside them.
2. Observing the sequence:
- The first square has a small hollow circle in the top-left corner.
- The second square has a small filled black circle in the center.
- The fourth square has a small filled black circle in the top-right corner.
3. The pattern seems to involve the position and fill of the small circle moving clockwise around the square corners and changing fill style.
4. The first circle is hollow at top-left, the second is filled in the center, and the fourth is filled at top-right.
5. The missing third figure should logically have a small hollow circle in the bottom-right corner to continue the pattern of moving clockwise and alternating fill.
6. Among the options:
- Option 1: Hollow circle in center (does not fit the pattern)
- Option 2: Filled circle in bottom-left (does not fit the hollow pattern)
- Option 3: Hollow circle in bottom-right (fits the expected pattern)
7. Therefore, the missing figure is option 3: a small hollow circle in the bottom-right corner.
Final answer: Option 3 (small hollow circle in bottom-right corner).
