The given sequence is: 10, 14, 18, 22.

This is an **arithmetic sequence** because the difference between consecutive terms is constant.

To find the general term \( a_n \) of an arithmetic sequence, we use the formula:

\[
a_n = a_1 + (n - 1) \cdot d
\]

Where:
- \( a_1 \) is the first term of the sequence,
- \( d \) is the common difference between consecutive terms,
- \( n \) is the term number we are looking for.

### Step 1: Identify the values
- First term \( a_1 = 10 \)
- Common difference \( d = 14 - 10 = 4 \)

### Step 2: General formula
Substitute \( a_1 \) and \( d \) into the formula:

\[
a_n = 10 + (n - 1) \cdot 4
\]
Simplifying:

\[
a_n = 10 + 4n - 4
\]
\[
a_n = 4n + 6
\]

### Step 3: Find the \( n \)-th term
The \( n \)-th term is given by the formula:

\[
a_n = 4n + 6
\]

So, for any value of \( n \), you can find the corresponding term in the sequence.
