Find the 11th term of this sequence. -10, 20, -40,

Okay just by looking at it the numbers go up By times 2

1). 10*2=20

2). 20*2=40

3). 40 *2=80

4). 80*2= 160

5). 160*2=320

6). 320*2=640

7). 640*2=1,280

8). 1,280*2=2,560

9). 2,560*2=5,120

10). 5,120*2=10,240

11). 10,240*2=20,480

But as we see every other number is negative

-10 20 -40 80 -160 320 -640 1,280 -2,560 5120 -10,240 20,480

20,480 is your answer!
