Purpose of explicit rule

Calculate any term directly without previous terms

Linear growth definition

Sequence increases by same amount each time

Linear decay definition

Sequence decreases by same amount each time

Explicit rule for linear growth

Vn=V0+nDV_n = V_0 + nD

Explicit rule for linear decay

Vn=V0nDV_n = V_0 - nD

What V0V_0 represents in explicit rule

Starting value

What DD represents in explicit rule

Common difference

Simple interest is example of

Linear growth

Flat rate depreciation is example of

Linear decay

Unit cost depreciation based on

Usage rather than time
