Question

what row comes next in the pattern?

Explanation:

Analyze the structure of each row

Row 1: Triangle, Circle, Triangle (1 triangle, 1 circle, 1 triangle)
Row 2: Triangle, Triangle, Circle, Triangle, Triangle (2 triangles, 1 circle, 2 triangles)
Row 3: Triangle, Triangle, Triangle, Circle, Triangle, Triangle, Triangle (3 triangles, 1 circle, 3 triangles)

Determine the pattern rule

Each row \(n\) consists of:

• \(n\) blue triangles
• 1 green circle
• \(n\) blue triangles

Predict the next row

For Row 4 (\(n = 4\)):

• 4 blue triangles
• 1 green circle
• 4 blue triangles

This forms a sequence of 9 shapes: Triangle, Triangle, Triangle, Triangle, Circle, Triangle, Triangle, Triangle, Triangle.

Answer:

The next row in the pattern consists of 4 blue triangles, followed by 1 green circle, followed by 4 blue triangles:
