This is an arithmetic sequence, where the difference between consecutive terms is constant. To find the common difference, subtract any term from the previous one:

$\text{Common difference} = 4 - 10 = -6$ Now, use the common difference of $-6$ to find the next term:

$\text{Next term} = -2 + (-6) = -8$

Thus, the next term in the sequence is $-8$.

Tip: In an arithmetic sequence, the formula for the $n$-th term is given by $a_n = a_1 + (n-1)d$, where $a_1$ is the first term and $d$ is the common difference.
