Figure Patterns

Subject: Mental Ability | Frequency: 1-2 questions per APPSC paper | Time: 45-60 sec/question


Introduction

Figure pattern questions present a sequence of figures with a visual pattern; you must predict the next figure or find the odd one out. APPSC commonly tests rotation-based series and pattern completion. This is purely a visual pattern recognition skill that improves with repetition — practice is the only shortcut.


Core Method

  1. Observe the sequence — study all given figures carefully
  2. Identify what changes between figures:
    • Position (rotation, shift)
    • Shape (addition, deletion, transformation)
    • Shading (filled, empty, half-filled)
    • Size (increasing, decreasing)
    • Count (number of elements)
  3. Determine the rule — what pattern governs the change?
  4. Apply the rule to predict the next figure
  5. Match with options — select the closest match
  6. Verify — ensure the rule holds for ALL given figures, not just two

Common Patterns

Rotation Patterns

PatternDescription
Clockwise rotationFigure rotates 45, 90, or other angles CW
Anticlockwise rotationFigure rotates CCW
Alternating rotationCW then ACW alternately

Element Changes

PatternDescription
AdditionOne new element added each step
DeletionOne element removed each step
ReplacementElement changes to different type
MovementElement shifts to different position

Shading Patterns

PatternDescription
Progressive fillSections fill one by one
Alternating shadeBlack <-> White alternating
Cyclic shadingShading rotates through sections

Counting Patterns

PatternDescription
Increasing countLines, dots, shapes increase (1,2,3...)
Decreasing countElements decrease
Constant countSame total, just rearranged

Worked Examples — Easy

Q1: Figures show a triangle rotating 90 degrees clockwise each step. Currently pointing right. What's next?

  • Up → Right → Down → Left (90 degrees CW cycle)
  • Currently pointing right → next: pointing down

Q2: Series shows: 1 dot, 2 dots, 3 dots, 4 dots, ?

  • Pattern: +1 dot per step
  • Answer: 5 dots

Q3: Square with a shaded quadrant moving clockwise: top-left, top-right, bottom-right, ?

  • Shading moves one quadrant clockwise each step
  • Answer: bottom-left shaded

Worked Examples — Medium

Q4: Pentagon with one marked side. Mark moves one side clockwise each step. Where after 4 steps from top?

  • Top → upper-right → lower-right → lower-left → upper-left
  • Answer: upper-left

Q5: Circle with 1 line, triangle with 2 lines, square with 3 lines, pentagon with ?

  • Shapes: increasing sides (circle, 3, 4, 5)
  • Lines: 1, 2, 3, ?
  • Answer: Pentagon with 4 lines

Q6: Matrix: Row 1: circle, triangle, square. Row 2: triangle, square, circle. Row 3: square, circle, ?

  • Each row contains all three shapes in different positions
  • Row 3 needs the missing shape: triangle

Worked Examples — Hard

Q7: Arrow right + dot above → Arrow down + dot right → Arrow left + dot below → ?

  • Arrow rotates 90 degrees CW each step
  • Dot position follows: above → right → below → left
  • Answer: Arrow up + dot on left

Q8: Fig 1: outer circle + inner triangle. Fig 2: outer square + inner circle. Fig 3: outer triangle + inner square. Fig 4: ?

  • Outer shapes: circle → square → triangle → circle (cycle)
  • Inner shapes: triangle → circle → square → triangle (cycle)
  • Inner shape becomes outer shape of next figure
  • Answer: Outer circle + inner triangle (cycle repeats)

Q9: 3x3 grid has a checkerboard pattern with one cell missing.

  • Rule: If (row + column) is even = one color; if odd = other color
  • Identify the missing cell's row and column, apply the rule
  • Answer: Determined by the (row+column) parity rule

Shortcuts & Tricks

ShortcutWhen to Use
Track ONE elementDon't track everything; focus on the most distinctive element
Rotation = count turns90 degrees CW = right turn; track cumulative rotation
Matrix: row + column checkIn 3x3 matrices, each row and column usually has all variants
Elimination firstRule out 2-3 options on one feature, then verify the remaining
Count sides/linesMany patterns are based on incrementing geometric properties
Overlay mentallyFor embedded figures, mentally place the target on the complex figure

Common Mistakes

  1. Tracking too many elements — focus on one changing element first, then verify others
  2. Ignoring rotation direction — CW and ACW rotations look similar but produce different results
  3. Missing subtle shading — half-shaded vs fully shaded sections are easy to confuse
  4. Wrong elimination — eliminating a correct option based on superficial check
  5. Not checking all given figures — pattern must hold for the ENTIRE sequence, not just the last 2

Exam Strategy

  • Practice figure series daily — this is a visual skill that improves with repetition
  • APPSC keeps difficulty at medium
  • Focus on rotation-based series and pattern completion — these are the most common
  • Time: 45-60 seconds per question
  • For figure series: identify the ONE most prominent change first, then verify with secondary changes

Practice Questions

  1. Arrow pointing East rotates 90 degrees ACW each step. After 3 steps? → E→N→W→S (South)
  2. Series: 2 sides, 3 sides, 4 sides, 5 sides, ? → 6 sides (hexagon)
  3. Dot moves: top-left, top-right, bottom-right, bottom-left, ? → top-left (cycle repeats)
  4. Shaded section in circle: 1/4, 2/4, 3/4, ? → 4/4 (fully shaded)
  5. Matrix with all shapes used: Row has circle and square, missing? → triangle
