One of the children bought their teacher a mathematical plant for the classroom windowsill. At the end of the first day it had increased its height by a factor of a half. At the end of the second day it had increased its height from the end of day 1 by a factor of a third. The class found that this pattern continued day after day. How many days did it take to grow to 10 times its original height? PLEASE HELP ITS A QUESTION DUE TOMMOROW
