In a figure series: Pentagon with 5 sides, Hexagon with 6 sides, Heptagon with 7 sides. What comes next?
Correct Answer:
A. Octagon with 8 sides
EXPLANATION
The number of sides increases by 1 each time: 5→6→7→8 sides.
A pattern alternates: Black triangle, White triangle, Black triangle. The 7th figure in the sequence will be?
Correct Answer:
A. Black triangle
EXPLANATION
Odd positions (1,3,5,7) have black triangles; even positions have white triangles.
In a size progression pattern: Small square, Medium square, Large square. If size increases by factor 2 each time, what is the ratio of the first to fourth figure's area?
Correct Answer:
A. 1:8
EXPLANATION
With factor 2 increase: 1st=1, 2nd=2, 3rd=4, 4th=8. Area ratio is 1:8.
A pattern shows: Square rotates 45°, then 90°, then 135°. What is the next rotation angle?
Correct Answer:
A. 180°
EXPLANATION
The rotation increases by 45° each time: 45°, 90°, 135°, so next is 180°.
In a series, the first figure has 2 circles, the second has 3 circles, and the third has 5 circles. Following this pattern, how many circles will the fourth figure have?

A figure shows: Square with 1 line inside, Square with 2 lines inside, Square with 3 lines inside, ?. How many lines in the 5th square?
Correct Answer:
B. 5 lines
EXPLANATION
Linear progression: Position n has n lines. 5th figure has 5 lines.
In a size progression: Small circle, Medium circle, Large circle, Very large circle, ?. The radius increases by 1 cm each time starting from 1 cm. What is the radius of the 5th circle?
Correct Answer:
B. 5 cm
EXPLANATION
Radii: 1, 2, 3, 4, 5 cm. The 5th figure has 5 cm radius.
A pattern alternates colors: Red, Blue, Red, Blue, ?. What is the 7th element?

A sequence shows: 2 dots, 4 dots, 8 dots, 16 dots, ?. Following the pattern, how many dots in the next figure?
Correct Answer:
B. 32 dots
EXPLANATION
Each figure doubles the number of dots (×2). 16 × 2 = 32 dots.
In a rotational pattern: Figure rotates 45° clockwise each step. If the initial figure faces North, which direction after 4 rotations?
Correct Answer:
B. South
EXPLANATION
4 rotations × 45° = 180°. North + 180° = South.
