To determine the equation for the perimeter of the given figures, let's analyze the pattern in the images and the table provided.

### Step 1: Analyze the Figures
Each figure is made up of triangles, and as you progress from Figure 1 to Figure 4, a new triangle is added each time.

- **Figure 1:** 1 triangle
- **Figure 2:** 2 triangles
- **Figure 3:** 3 triangles
- **Figure 4:** 4 triangles

### Step 2: Look at the Perimeter
From the table, the perimeters are listed as follows:

- **Figure 1:** 3 units
- **Figure 2:** 4 units
- **Figure 3:** 5 units
- **Figure 4:** 6 units

### Step 3: Establish a Pattern
Looking at the dataTo determine the equation for the perimeter of the given figures, let's analyze the pattern in the images and the table provided.

### Step 1: Analyze the Figures
Each figure is made up of triangles, and as you progress from Figure 1 to Figure 4, a new triangle is added each time.

- **Figure 1:** 1 triangle
- **Figure 2:** 2 triangles
- **Figure 3:** 3 triangles
- **Figure 4:** 4 triangles

### Step 2: Look at the Perimeter
From the table, the perimeters are listed as follows:

- **Figure 1:** 3 units
- **Figure 2:** 4 units
- **Figure 3:** 5 units
- **Figure 4:** 6 units

### Step 3: Establish a Pattern
Looking at the 
- The perimeter increases by 1 unit as you move from one figure to the next.

### Step 4: Determine the Equation
The perimeter increases linearly by 1 unit for each additional triangle, and the base perimeter starts at 3 units. This suggests that the perimeter \( P \) for figure \( n \) can be expressed as:

\[
P(n) = 2 + n
\]

Where:
- \( P(n) \) is the perimeter of figure \( n \).
- \( n \) is the number of triangles (which is also the figure number).

### Final Equation:
\[
P(n) = n + 2
\]

This equation reflects that each additional triangle adds 1 unit to the perimeter, starting from 3 units for Figure 1.
