Séquence vs. série

The French words séquence and série both translate to sequence or series in English, but they are used in distinct contexts. This explanation clarifies the differences between these two terms with examples.

Séquence

B1
Séquence is generally used to describe a sequential order of events or elements, often tied to a clear progression or continuity. It is commonly used in contexts such as films, education, or science to describe a logical or chronological succession.
La séquence finale du film était pleine de suspense.
(The final sequence of the film was full of suspense.)
Lélève doit compléter une séquence dexercices pour comprendre le sujet.
(The student must complete a sequence of exercises to understand the topic.)
En biologie, la séquence dADN est cruciale pour comprendre le code génétique.
(In biology, the DNA sequence is crucial to understanding the genetic code.)

Série

A2
Série refers to a set or collection of items, events, or phenomena that are related or follow one another, but are not necessarily connected by a strict logical or chronological order. It is widely used in entertainment, mathematics, and other contexts.
Jadore regarder cette série télévisée tous les soirs.
(I love watching this TV series every evening.)
Une nouvelle série détudes sera publiée lannée prochaine.
(A new series of studies will be published next year.)
En mathématiques, une série peut être la somme de termes qui suivent une règle définie.
(In mathematics, a series can be the sum of terms that follow a defined rule.)

Summary

Though séquence and série can both refer to an order of things, séquence implies a logical or chronological progression and is often used in film, education, or science. In contrast, série is broader, suggesting a set or group of related elements without requiring strict order and is common in entertainment, mathematics, and general descriptions.
