It is the law of doubling every day, that is, the law of growth rate of 100% every day.

For example, 1, 100, 2,200,3,400 and 4,800.5, 1600. ...................

Double daily = (200-100)/200 * 2 =1.

Double daily =(400-200)/400*2= 1

Double daily =(800-400)/800*2= 1

Double daily = (1600-800)/1600 * 2 =1

..............................................

Daily increase = (200-100)/100 *100% =100%.

Daily increase = (400-200)/200 *100% =100%.

Daily growth rate = (800-400)/400 *100% =100%

Daily increase (1600-800)/800 *100% =100%.
