A sequence adds a new shape on the outside ring each step: 1 shape, then 1+6=7, then 7+12=19. How many shapes in step 4?
Answer: 37
Each ring adds 6 more shapes than the previous ring: ring 1=6, ring 2=12, ring 3=18; total at step 4 = 19+18=37.
In a shape sequence, circles are replaced by squares after every 3 steps. Starting with a circle at step 1, what is the shape at step 10?
Answer: Circle
Steps 1–3: circle; steps 4–6: square; steps 7–9: circle; step 10 starts a new square phase — wait: step 10 = square.
A figure sequence shows arrows rotating 45° anticlockwise each step. Starting pointing North, what direction does the arrow point at step 5?
Answer: West
5 steps × 45° anticlockwise = 225° anticlockwise from North; that is equivalent to pointing West.
Each figure in a sequence has one more line of symmetry than the previous. The first figure has 1 line of symmetry. How many does the 4th figure have?
Answer: 4
Starting at 1 and adding 1 each step: 1, 2, 3, 4 — the 4th figure has 4 lines of symmetry.
A pattern sequence contains: pentagon, hexagon, pentagon, hexagon, ___. What is the 7th figure?
Answer: Pentagon
The sequence alternates pentagon/hexagon; odd positions are pentagons, and 7 is odd — so the 7th figure is a pentagon.
In a sequence of figures, the number of dots inside decreases: 10, 8, 6, 4, ___. What is next?
Answer: 2
The sequence decreases by 2 each step: 10−2=8, 8−2=6, 6−2=4, 4−2=2.
