In summary, the conversation discusses a shortcut for finding the amount after a certain number of years. However, it is noted that the question is too general and lacks enough information to have a unique solution. Different functions can produce different results at 15 years. It is suggested that additional restrictions may be needed for a more specific solution.

Homework Statement
In 8 years, amount becomes 17 times of P. So in 15 years, amount becomes how much?
Relevant Equations
##\large \frac{8}{?} = \frac{17-1}{n_{2}-1} → \frac{8}{15} = \frac{16}{n-1} →\normalsize n = 31 \; times ##
In 8 years, amount becomes 17 times of P. So in 15 years, amount becomes how much?

A) This is the shortcut:

##\large \frac{8}{?} = \frac{17-1}{n_{2}-1} → \frac{8}{15} = \frac{16}{n-1} \normalsize → n = 31 \; times ##

Your question is too general to have a unique solution. There are many functions that meet your 8 year requirement that will have different results at 15 years. Perhaps you have left out some additional restrictions on the type of function (like it has to be linear, for example)?

As @DaveE says, it depends on what type of model you're studying and supposed to be applying. A more common model for growth is exponential, ##P = P_0 e^{at}## or ##P/P_0 = e^{at}## in which case you're expected to use the given value of ##P/P_0## first to solve for the rate constant ##a##.
