Find the next four terms in the arithmetic sequence. a - 6, a - 2, a + 2, ...

The next four terms in the sequence are a + 6, a + 10, a + 14, a + 18. This is because you are adding 4 to what is being done to "a" each time. If you look at the pattern, you’ll see that 4 is being added and the "a" stays the same.
