Using an Explicit Rule for Geometric Growth or Decay (VCE SSCE General Mathematics): Flashcards

$V_n = R^n \times V_0$

Initial value or starting value

Common ratio or growth/decay multiplier

$R > 1$

$R < 1$

$R = 1 + \frac{r}{100}$

$R = 1 - \frac{r}{100}$

Calculate difference between consecutive terms

Round up to the next whole year

Choose the value that makes practical sense in context
