NNAT3 Serial Reasoning 2 — Questions and Answers
Question 1: A matrix shows shapes growing by adding one side each step: triangle, square, pentagon, ___. What comes next?
- Hexagon (Correct answer)
- Circle
- Triangle
- Octagon
Correct answer: Hexagon
Each shape gains one side per step, so after a pentagon (5 sides) comes a hexagon (6 sides).
Question 2: In a 3×3 grid, each row contains a large, medium, and small circle. The first row has large-medium-small, the second has medium-small-large. What order does the third row follow?
- Small-large-medium (Correct answer)
- Large-small-medium
- Medium-large-small
- Small-medium-large
Correct answer: Small-large-medium
Each size shifts one position to the left each row, so the third row is small-large-medium.
Question 3: A sequence shows: filled square, empty square, filled square, empty square, ___. What is the missing figure?
- Filled square (Correct answer)
- Empty circle
- Empty square
- Filled circle
Correct answer: Filled square
The pattern alternates filled and empty squares, so the fifth figure is a filled square.
Question 4: Each column in a matrix rotates a shape 90° clockwise. The top-left shows an arrow pointing up; the top-middle shows it pointing right. What does the top-right cell show?
- Arrow pointing down (Correct answer)
- Arrow pointing left
- Arrow pointing up
- Arrow pointing right
Correct answer: Arrow pointing down
A 90° clockwise rotation from 'right' yields 'down'.
Question 5: A row pattern shows: 1 dot, 3 dots, 5 dots, ___. How many dots come next?
- 7 dots (Correct answer)
- 6 dots
- 8 dots
- 4 dots
Correct answer: 7 dots
The sequence increases by 2 each time (odd numbers), so after 5 comes 7.
Question 6: In a 3×3 matrix, shading moves one cell to the right each row: row 1 shades column 1, row 2 shades column 2. Which cell is shaded in row 3?
- Column 3 (Correct answer)
- Column 1
- Column 2
- No cell
Correct answer: Column 3
The shaded cell shifts one column to the right each row, landing on column 3 in row 3.
Question 7: A series shows shapes that flip horizontally each step. Step 1 has a right-pointing arrow; step 2 has a left-pointing arrow; step 3 has ___.
- Right-pointing arrow (Correct answer)
- Up-pointing arrow
- Left-pointing arrow
- Down-pointing arrow
Correct answer: Right-pointing arrow
The shape alternates between right and left with each horizontal flip, returning to right-pointing at step 3.
