Final answer:
The 5th term in the arithmetic sequence is -10.
Step-by-step explanation:
The 5th term in an arithmetic sequence can be found using the formula:
an = a1 + (n-1) * d
where an is the nth term, a1 is the first term, n is the number of terms, and d is the common difference.
Given that the second term is -2 and the common difference is -2, we can substitute these values into the formula:
a5 = -2 + (5-1) * -2
a5 = -2 + 4 * -2
a5 = -2 - 8
a5 = -10
Therefore, the 5th term in the arithmetic sequence is -10.
