EDIT: Actually, I suppose they would. I think you're right. Ganesh even said the number of pairs at the start, didn't he?
]]>Oops, my bad!
What I think:
month a j b t
1) 1 1
2) 1 1 2
3) 1 1 1 3
4) 2 1 2 5
5) 3 2 3 8
6) 5 3 5 13
7) 8 5 8 21
8) 13 8 13 34
9) 21 13 21 55
10) 34 21 34 89
With the letters representing the same things as Jane's, in pairs. And 't' being the total number of pairs.
]]>EDIT: Anyway, Ive just made a re-calculation on the revised assumption that the juveniles can reproduce as soon as they reach maturity (just add a blue arrow from each JJ to the BB below it in my diagram above). Guess what answer I got.
288.
]]>AA = Adult (mature) pair, JJ = Juvenile (one-month old) pair, BB = Baby (newborn) pair
Starting with AA:
Total rabbits at end of 10 months = 2×(28 + 13 + 19) = 120.
]]>Notice any patterns?
Fibonacci!
]]>Huh? Is it that simple ... I must have made a mistake.
]]>To MathsIsFun, the mature rabbits breed every month, not every two.
