To address the given problem, we need to examine the structure of the array and determine the value of the missing element, denoted by "?" in the array. Here is the provided array with a missing element:
[tex]\[
\begin{array}{rrrr}
2 & -3 & 9 & 5 \\
8 & ? & 3 & 7 \\
-4 & 2 & 4 & -6 \\
5 & 2 & 8 & 1 \\
\end{array}
\][/tex]
To find the value of the missing element, let's analyze what we know about the array based on the given result:
[tex]\[
\begin{array}{rrrr}
2 & -3 & 9 & 5 \\
8 & None & 3 & 7 \\
-4 & 2 & 4 & -6 \\
5 & 2 & 8 & 1 \\
\end{array}
\][/tex]
From examining the structure above, we interpret the missing value "?" as "None."
Thus, the missing value in the array is:
[tex]\[
\text{?} = \text{None}
\][/tex]
In conclusion, the value of the missing element in the given array is 'None'.
