What is a finite geometric series?

A sequence where each term after the first is multiplied by a constant ratio, with a limited number of terms

A series that continues indefinitely

A sequence where each term is multiplied by a constant

A series without a common ratio

If a series has a common ratio of r=0.5, what happens to the series terms over time?
