To create a vector in MATLAB with a specific starting point, increment, and ending point, you can use the colon operator `:` or the `linspace` function. For this problem, we need to create a vector \(X\) starting from 2, with an increment of 3, and ending at 29.

Here is how you can put it into MATLAB:

### MATLAB Code

```matlab
% Define the starting value, increment, and ending value
startValue = 2;
increment = 3;
endValue = 29;

% Create the vector using the colon operator
X = startValue:increment:endValue;

% Display the 5th element
X5 = X(5);
fprintf('X5 = %d\n', X5);

% Display the 8th element
X8 = X(8);
fprintf('X8 = %d\n', X8);
```

### Explanation:
1. **Vector Creation**:  
   - `X = startValue:increment:endValue;` creates a vector starting from 2, incrementing by 3, and ending at 29. The colon operator `:` is commonly used for creating regularly spaced vectors in MATLAB.
   
2. **Accessing Elements**:
   - `X(5)` accesses the 5th element of the vector `X`.
   - `X(8)` accesses the 8th element of the vector `X`.

3. **Displaying Results**:
   - `fprintf` is used to print formatted data to the command window. It shows the 5th and 8th elements of the vector.

### Output:
Running the above code in MATLAB will give:
- `X5 = 14`
- `X8 = 23`
