In an arithmetic sequence, the common difference is the difference between any two consecutive terms.
Let's calculate the common difference for the given sequence:
- The first term is \(4\).
- The second term is \(10\).
- The third term is \(16\).
- The fourth term is \(22\).
Now, we find the difference between the second term and the first term: \[ 10 - 4 = 6 \]
Next, we find the difference between the third term and the second term: \[ 16 - 10 = 6 \]
Finally, we find the difference between the fourth term and the third term: \[ 22 - 16 = 6 \]
Since the difference is consistent across all pairs of consecutive terms, the common difference of the arithmetic sequence is:
\[ \boxed{6} \]
