I think there are more protests in modern day times rather then in the earlier time periods, because people are now more aware of their rights, and how they influence the way their country is run. Also, nowadays most countries are democratic, meaning that everyone can express their opinions and people protest as a way of expressing their opinions about something.
Answer:
"Multiply the previous value by 2"
Step-by-step explanation:
Let's check the first 2 terms for all the answer choices.
1. Add
to the previous value:

Doesn't match.
2. Subtract
from the previous value:

Doesn't match.
3. Divide the previous value by 2:

Doesn't match.
4. Multiply the previous value by 2:

DOES WORK!
Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
6x + 7(1-x) = -4(x-4)
6x + 7 - 7x = -4x + 16
-x + 7 = -4x + 16
-x + 4x = 16 - 7
3x = 9
x =9/3
x = 3
