Outcomes

3.2.5

use recursion to generate a geometric sequence

3.2.6

display the terms of a geometric sequence in both tabular and graphical form and demonstrate that geometric sequences can be used to model exponential growth and decay in discrete situations

3.2.7

deduce a rule for the nth term of a particular geometric sequence from the pattern of the terms in the sequence, and use this rule to make predictions

3.2.8

use geometric sequences to model and analyse (numerically, or graphically only) practical problems involving geometric growth and decay
