It is a geometric series with the factor -2. The next term is (-40)(-2)=80
Then *-2 is -160.
True.

Notice what is happening as you go from term to term...do you see that you are multiplying by -2 each time? This is called a geometric sequence.
Thus if we continue the pattern, we will get
...-40, 80, -160...
TRUE
