Answer 1

To complete the missing values in the table using the arithmetic sequence formula \( a_n = 5 + (n - 1) \cdot 2 \), we first need to compute \( y \) for the given values of \( x \) (which corresponds to \( n \)).

### For \( x = 2 \):
Substitute \( n = 2 \) into the formula:

\[
a_2 = 5 + (2 - 1) \cdot 2
\]
\[
a_2 = 5 + 1 \cdot 2
\]
\[
a_2 = 5 + 2 = 7
\]

So, when \( x = 2 \), \( y = 7 \).

### For \( x = 4 \):
Substitute \( n = 4 \) into the formula:

\[
a_4 = 5 + (4 - 1) \cdot 2
\]
\[
a_4 = 5 + 3 \cdot 2
\]
\[
a_4 = 5 + 6 = 11
\]

So, when \( x = 4 \), \( y = 11 \).

### Completed Table:
Now we can fill in the missing values:

| x | y |
|-----|-----|
| 2 | 7 |
| 4 | 11 |
