#### Answer

$14, 10, $ and $6$ may be the first three terms of an arithmetic sequence because even though it may appear that we are subtracting $4$ instead of adding $4$ to get the next term, we are actually adding the common difference which is $-4$.

#### Work Step by Step

RECALL:
An arithmetic sequence has a common difference $d$. The common difference can be found using the formula:
$d=a_n- a_{n-1}$
where
$a_{n-1}$ and $a_n$ are consecutive terms of the sequence
$14, 10, $ and $6$ may be the first three terms of an arithmetic sequence because they have a common difference of $-4$.
Note that:
$10-14=-4$ and $6-10=-4$
Therefore, the numbers $14, 10,$ and $6$ may be the first three terms of an arithmetic sequence. It appears we are subtracting $4$ instead of adding $4$, but note that subtracting $4$ is the same as adding $-4$.
