### 451: Growth Rate

Population of organism after n minutes is $P(n) = k*9^{(\frac{n}{2})}$.
What is the growth factor?

... algebraically stated, what is the ratio of P(t+1):P(t)?

1. Thanks for posting this! Your question is better expressed than mine (more 'real-world'). Furthermore my suggested solution was uninspired. Much better to rewrite 9^(n/2) as 3^n...
