Answer:
after 4 cuts there are 8 pieces. A = 2
Explanation:
Every time you cut the piece of paper you double the amount of pieces of paper because you are splitting each one into two. i am not sure what nth means but whatever number it means you multiply by two.
The value of digit A is 2. It is hard to explain but I will try my best :) Look at the other side it starts with ends with two and since the sum of every consecutive three digits equals 11 then it needs to be then the start of the series of number has to be the same as the end. But it should be this if you fill in all the boxes.
2-3-3-2-3-3-2-3-3-2-3-3-2
