Final answer:
The correct form of 'gustar' to use in the sentence is 'gustan' because 'conciertos' is plural. 'Gustar' is a verb used to express liking or enjoyment in Spanish.
Step-by-step explanation:
The correct form of gustar to fill in the blank in the sentence 'Te ____ los conciertos' is gustan.
'Gustar' is a Spanish verb that expresses liking or enjoyment, and it is used in a different way than in English. In Spanish, when talking about something that pleases someone, we use 'gustar' in the third person, matching the verb form with the thing that is liked, not the person who likes it.
For example, if someone likes concerts, we say 'Le gustan los conciertos' (he/she likes concerts). In this case, 'te' is the indirect object pronoun for 'you,' and since 'conciertos' is plural, we use the third person plural form of 'gustar,' which is 'gustan'.
