Question

what shape comes next?

Explanation:

Identify the sequence of shapes

The sequence of shapes shown is:

1. Triangle (pink)
2. Spade (purple)
3. Triangle (pink)
4. Spade (purple)
5. Spade (purple)
6. Triangle (pink)
7. Spade (purple)
8. Spade (purple)
9. Spade (purple)
10. Triangle (pink)
11. Blank box

Analyze the pattern structure

Let \(T\) represent a Triangle and \(S\) represent a Spade. The sequence is:

$$ T, S, T, S, S, T, S, S, S, T, \dots $$

This is a growing pattern where each pink triangle separates groups of purple spades. The number of spades in each group increases by 1 each time:

• First group: 1 spade (\(S\))
• Second group: 2 spades (\(S, S\))
• Third group: 3 spades (\(S, S, S\))

Determine the next shape

Following the pink triangle at position 10, a new group of spades must begin. The fourth group will contain 4 spades. Therefore, the shape immediately following the triangle at position 10 must be a spade.

Answer:

• (A) pink triangle
• (B) purple spade (Correct answer)
