SEQUENCES
GEOMETRIC SEQUENCES
Application type questions involves growth and decay of discrete variables.
Eg: population (increase/decrease)
financial investments (increase/decrease)
depreciation/appreciation
interest earned
Geometric Growth
1. Geometric growth or increase is expressed as a percentage increase
2. Common ratio (r)= 1+% increase
3. r values are greater than 1, for example, an 8% increase gives r =1.08
Geometric Decay
1. Geometric decay or decrease is expressed as a percentage decrease.
2. Common ratio (r) = 1 - % decrease
3. r values are less than 1, for example, an 8% decrease gives r = 0.92
COMPOUND INTEREST
EXAMPLES
