Given:

The arithmetic sequence is represented in the table.

The general form of the arithmetic sequence is given by

[tex]a_n=a_1+(n-1)d[/tex]

We need to determine the value of the missing term.

First term:

From the table, we need to determine the first term of the arithmetic sequence.

From the table, the value of the first term is 3.

Thus, [tex]a_1=3[/tex]

Hence, the first term is 3.

Common difference:

From the table, we can determine the common difference of the arithmetic sequence.

Thus, we have;

12 - 3 = 9

Hence, the common difference is [tex]d=9[/tex]

Value of the missing term:

The value of the term 45 can be determined by substituting n = 45 in the general form [tex]a_n=a_1+(n-1)d[/tex]

Thus, we have;

[tex]a_{45}=3+(45-1)(9)[/tex]

[tex]a_{45}=3+(44)(9)[/tex]

[tex]a_{45}=3+396[/tex]

[tex]a_{45}=399[/tex]

Hence, the value of the term 45 is 399.

Thus, the value of the missing term is 399.
