Leo was a mathematician-cum-magician. In one of his shows, he produced rabbits each time he put his hand in his hat. In the first and second go, he brought up 1 rabbit each. In the third go, he brought up 2 rabbits. The next go produced 3 rabbits. A smart kid, like you, from the audience understood the pattern and guessed the number of rabbits that Leo would bring up in the next go. What did the smart kid guess?
5
The number of rabbits produced at each stage followed the Fibonacci sequence.
1,1,2,3,...
The next number would therefore be 2 + 3 = 5
