Hello there!

Answer:

2

Explanation:

In order to find the 5th term in the sequence, you would need to find the number that multiplies to get the next number.

In this case, that number would be "-2"

The reason why it's "-2" is because when you multiply 0.125, you would get -0.25. And, when you multiply -0.25 by -2, you would get 0.5.

You would pretty much keep multiplying by 2 until you get the 5th term.

________________

0.125 ------> 1st term

× -2

-0.25 ------> 2nd term

× -2

0.50 ------> 3rd term

× -2

-1 ------> 4th term

× -2

2 ------> 5th term
