An infinite series is a sum of the terms of an infinite sequence, which continues indefinitely without terminating. This concept is crucial in mathematics, particularly in calculus and analysis, as it allows for the representation of functions and solutions to equations through sums that converge to a specific value. Infinite series were explored extensively during the Hellenistic period, leading to advancements in mathematical thought and applications that laid the groundwork for later developments in science and mathematics.
