Answer 1

The second option: 512, -2048
You multiply number before by 4 to get the next number.

Answer 2

512,-2048

Explanation:

We are given that a pattern

2,-8,32,1-28,..

We have to find two next numbers in this given pattern

`a_=2,a_2=-8,a_3=32,a_4=-128`

Next term is -4 times the previous term

`a_n=-4a_(n-1)`

`a_5=-4(-128)=512`

`a_6=-4(512)=-2048`

Hence, option B is true.

Answer:512,-2048
