Definition

The ratio test is used to determine whether an infinite series converges absolutely, converges conditionally, or diverges by examining the limit of the ratio of consecutive terms.

Absolute Convergence: A type of convergence where both positive and negative terms in a series converge individually.

Conditional Convergence: A type of convergence where rearranging the order of terms in a convergent series can change its sum.

Divergence Test: A method used to determine whether an infinite series diverges by checking if its terms do not approach zero.
