if structure 1 has 2 dots, structure 2 has 5 dots, structure 3 has 10 dots, structure 4 has 17 dots how will structure 5 look like

To determine the pattern, we can start by examining the relationship between the number of dots in each structure and their position in the sequence:

- **Structure 1:** 2 dots  
- **Structure 2:** 5 dots  
- **Structure 3:** 10 dots  
- **Structure 4:** 17 dots  

### Step 1: Identify the pattern in the sequence of dots.
Let's look at the differences between consecutive numbers of dots:

- From Structure 1 to Structure 2: \( 5 - 2 = 3 \)  
- From Structure 2 to Structure 3: \( 10 - 5 = 5 \)  
- From Structure 3 to Structure 4: \( 17 - 10 = 7 \)  

The differences between the number of dots are increasing by 2 each time (3, 5, 7).

### Step 2: Predict the number of dots in Structure 5.
The next difference should be \( 7 + 2 = 9 \).  
Thus, the number of dots in Structure 5 will be:

\[ 17 + 9 = 26 \]

### Conclusion:
Structure 5 will have 26 dots.

This sequence is based on the pattern where the difference between consecutive structures increases by 2 each time. If visualizing, the structure might involve dots arranged in a way where each new structure adds more dots in a specific manner, possibly around a central point or along expanding layers.
