Assume that a long thin strip of paper stretched out in front of you, left to right. Suppose the ends in your hands and placing the right hand end on top of the left. Now press the strip flat so that it is folded in half and has a crease. Repeat the entire operation on the new strip two more times.
How many creases are there?
How many creases will there be if the operation is repeated 10 times in total?
Can you find out a way of predicting how many creases there will be if we could repeat the method 50 times?
