A letter–shape code in an abstract test maps: A=circle, B=square, C=triangle. The sequence reads A, B, C, A, B, ___. What comes next?
Answer: C
The pattern cycles A→B→C repeatedly; after B at position 5, the next is C at position 6.
In an abstract sequence, odd figures are outlined and even figures are filled. The 12th figure is ___.
Answer: Filled
12 is an even number, so the 12th figure is filled.
A sequence shows shapes that each have one fewer corner than the previous: octagon, heptagon, hexagon, pentagon, ___.
Answer: Square
Each step removes one corner: 8→7→6→5→4 corners, and a shape with 4 corners is a square.
Each step in a sequence, a shape is rotated 90° and its color inverted (black↔white). Starting with a black shape at 0°, what is the state after 6 steps?
Answer: Black, 270°
6 × 90° = 540° = 180°; color flips 6 times (even) returning to black — so the shape is black at 180°... wait: 6 rotations of 90° = 540° mod 360° = 180°; 6 color inversions (even) = back to black. Answer: Black, 180°.
An abstract sequence doubles the perimeter at each step. The first figure has perimeter 4 units. What is the perimeter at step 4?
Answer: 32
Step 1=4, step 2=8, step 3=16, step 4=32 — the perimeter doubles each time.
In a tiling pattern, each row has one more tile than the row above: Row 1 has 3 tiles, Row 2 has 4, Row 3 has 5. How many tiles are in Row 6?
Answer: 8
Row n has 3+(n−1) tiles; Row 6 has 3+5=8 tiles.
