Common Ratio: The common ratio in an infinite geometric series refers to the constant value that each term is multiplied by to get to the next term.
Sum of Finite Geometric Series: This refers to finding the sum of a specific number of terms in a geometric series instead of adding up an infinite number of terms.
Convergence/Divergence: These terms describe whether an infinite geometric series approaches a finite value (converges) or goes towards positive or negative infinity (diverges) as more terms are added.
