Answer: -4

Explanation:

Two unlike signs automatically means to just subtract. So, now it looks like 8-12.
Subtract the smaller number from the larger number, 12-8, which equals to four.
But keep the sign of the larger value, which was 12, and twelve had a negative sign in he beginning, so 8+(-12) = -4.

Hope this helps, please mark as brainliest!

Enter a recursive rule for the geometric sequence. 10, −80, 640, −5120, ...<br><br> a(1)=<br> a(n)=
Liula [17]
The recursive formula would be:
a_1=10&#10;\\a_{n}=a_{n-1} \times (-8)

This is because the first term, a₁, is 10.  A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio.  The common ratio, or the number that each term is multiplied by, is -8.
