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!

its 50 miles away from the starting point

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
