Answer :

To solve the problem given by the table, let's carefully analyze the values. The task is to identify and complete the missing value in the table while keeping the existing numbers as they are. Here is the table again for reference:

[tex]\[ \begin{array}{l|l} 3423 & \frac{28}{3} \\ 14 & \\ 4520 & 18 \\ \end{array} \][/tex]

Step-by-Step Solution:

1. First Row:
- The first row is given as [tex]\( 3423 \)[/tex] on the left and [tex]\(\frac{28}{3}\)[/tex] on the right.
- The value [tex]\(\frac{28}{3}\)[/tex] is equivalent to approximately [tex]\(9.333333333333334\)[/tex].

2. Second Row:
- The second row has [tex]\( 14 \)[/tex] on the left and a missing value on the right.

3. Third Row:
- The third row has [tex]\( 4520 \)[/tex] on the left and [tex]\( 18 \)[/tex] on the right.

Given these points, the aim is to fill in the missing value in such a way that it conforms to the pattern established by the other values.

Combining the given values together, we can complete the table as follows:

[tex]\[ \begin{array}{l|l} 3423 & 9.333333333333334 \\ 14 & \boxed{} \\ 4520 & 18 \\ \end{array} \][/tex]

The result provided earlier lists the values as:
1. [tex]\( 3423 \)[/tex]
2. [tex]\( 9.333333333333334 \)[/tex] (i.e., [tex]\(\frac{28}{3}\)[/tex])
3. [tex]\( 14 \)[/tex]
4. [tex]\( 4520 \)[/tex]
5. [tex]\( 18 \)[/tex]

So, by identifying what is present and what is not, it can be concluded that:

[tex]\[ \boxed{} = \text{This value is not explicitly listed} \][/tex]

Therefore, for the incomplete value in the second row, we have no additional clues required from the numerical data provided. The values can be returned collectively as:

[tex]\[ (3423, 9.333333333333334, 14, 4520, 18) \][/tex]

Conclusively:
- The missing right-hand value for the row containing 14 must be explicitly considered unavailable based on the given combined results, which summarized to accurate matches of the other observed categories.

Thus, according to the reconstructive approach from understanding the relationships, the complete table is:
[tex]\[ \begin{array}{l|l} 3423 & 9.333333333333334 \\ 14 & \boxed{} \\ 4520 & 18 \\ \end{array} \][/tex]
