So this problem is a real life problem involving Fibonacci sequence. Because all adults get baby each month and little rabbit grows up each month. When you make a chat, you find out that the n term equal to n-1 plus n-2. N-1 is the number of babies;N-2 is the number of adult babies. And you need to find or calculate the 12th term of Fibonacci sequnce with the starting term of the first "one" 1,1,2,3,5,8,,13,21,34,55,89,144. And 144 is the twelve term which is your answer ☆ :.。. o(≧▽≦)o .。.:
