Answer:

Explanation:
This sequence will have a pattern. Our goal is to try and find this pattern.
Our first two numbers are -45 and 9. The first relationship between these numbers that pops into my mind is 5.
. However, we go from -45 to 9. This means we have to divide by -5.

Let's check this actually is what the sequence is. It would be true if
.

So -5 is the divisor.
To find the next term in the sequence, we divide -1.8 by -5.

Hope this helped!
