The common difference in an arithmetic sequence is found by subtracting any term from the term that follows it.

In the given sequence: $19, 27, 35, \dots$

Let's subtract the first term from the second term: $d = 27 - 19 = 8$

Now, let's verify by subtracting the second term from the third term: $d = 35 - 27 = 8$

Since the difference between consecutive terms is the same, the common difference is $\mathbf{8}$.
