The sequence doubles each time: 3 × 2 = 6, 6 × 2 = 12, 12 × 2 = 24, so 24 × 2 = 48.
The pattern alternates between an upward triangle (▲) and a downward triangle (▼). After ▼, the next shape should be ▲.
The triangle, square, and pentagon are polygons (shapes with straight sides), while the circle has no straight sides, making it the odd one out.
The pattern alternates between a square and a circle. After "Circle," the next shape should be a square.
The sequence increases by 3 each time (3 + 3 = 6, 6 + 3 = 9, 9 + 3 = 12). So, 12 + 3 = 15.
