Explanation:
Verbs in the infinitive form are not conjugated and do not indicate anything about who is performing an action or at what point in time the action is taking place. In my words, When the subject pronoun is in plural, the verb ends in (S). Such as vimos or visteis (See). Usually, for the subject pronoun They, the verb ends in (N). Such as Fueron or Dieron (to Have or to Give). Please correct me if i'm wrong and Hopefully I was able to help you :)
