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
