Understanding the Visual Pattern: Initial Observations
Examining the Given Shapes and Their Square Counts
The pattern begins with a shape labeled S=1, which contains 3 squares. As the shape number increases to S=2, the total squares increase to 8. Continuing this progression, S=3 contains 15 squares. These initial data points are critical in identifying the relationship between the shape number (S) and the total number of squares.
Summary of the initial data:
- S=1: 3 squares
- S=2: 8 squares
- S=3: 15 squares
From these observations, we can analyze the differences and attempt to deduce a formula or rule governing the pattern.

Analyzing the Pattern: Differences and Sequences
Calculating the Differences Between Sequential Shapes
To understand how the number of squares increases, let's examine the differences:
- From S=1 to S=2: 8 - 3 = 5
- From S=2 to S=3: 15 - 8 = 7
The differences are 5 and 7, which suggests a pattern in the incremental increase.
Next step: Check if the pattern continues by hypothesizing the next difference.

Identifying the Pattern in Differences
The differences themselves seem to follow a sequence: 5, 7, perhaps progressing by increasing odd numbers:
- 5 (from S=1 to S=2)
- 7 (from S=2 to S=3)
Assuming the pattern continues with the next difference increasing by 2:
- Next difference: 9
Applying this to find the number of squares at S=4:
- 15 + 9 = 24
Therefore, the pattern in differences appears to follow an odd number sequence starting from 5, increasing by 2 each time.

Deriving the Formula for the Number of Squares
Given the sequence:
- S=1: 3 squares
- S=2: 8 squares
- S=3: 15 squares
- S=4: 24 squares (projected)
We can attempt to find a direct formula for the total number of squares (T) at any shape S.
Step 1: Recognize the pattern in total squares.
Let's look for a quadratic formula, as the second differences are constant (they increase by 2 each time).
Step 2: Calculate the second differences.
- First differences: 5, 7, 9
- Differences of the first differences: 2, 2
Constant second difference indicates that T(S) is quadratic in S.
Step 3: Express T(S) as a quadratic formula:
T(S) = aS² + bS + c
Using known values:
- For S=1: a(1)² + b(1) + c = 3
- For S=2: 4a + 2b + c = 8
- For S=3: 9a + 3b + c = 15
Now, solve these equations:
- a + b + c = 3
- 4a + 2b + c = 8
- 9a + 3b + c = 15
Subtract equation 1 from equation 2:
(4a - a) + (2b - b) + (c - c) = 8 - 3
3a + b = 5 ...(i)
Subtract equation 2 from equation 3:
(9a - 4a) + (3b - 2b) + (c - c) = 15 - 8
5a + b = 7 ...(ii)
Subtract (i) from (ii):
(5a - 3a) + (b - b) = 7 - 5
2a = 2
a = 1
Using a=1 in (i):
3(1) + b = 5
3 + b = 5
b = 2
Using a=1 and b=2 in equation 1:
1 + 2 + c = 3
c = 0
Final formula:
T(S) = S² + 2S
Check for S=1:
1 + 21 = 3 ✔️
S=2:
4 + 4 = 8 ✔️
S=3:
9 + 6 = 15 ✔️
Thus, the pattern is governed by the formula:
T(S) = S² + 2S

Answering the Question: What Is the Next Shape S=4?
Using the derived formula T(S) = S² + 2S, calculate for S=4:
T(4) = 4² + 24 = 16 + 8 = 24
Therefore, S=4 will contain 24 squares.
This continues the pattern smoothly, confirming the consistency of the formula and the pattern's logic.
