If the sentence is <em>They enjoyed a snack and then finished their homework </em>the tense is correct in both parts.You are giving two finished actions in a sequence one after the other, which is correct. You join the two parts by using <em>then,</em> which is also right.What I think could make it better would be to use the personal pronoun <em>they</em> again as in: <em>They enjoyed a snack and then they finished their homework</em>

Explanation:
Any time an object is in motion, it is both producing energy and, in many cases, expending energy.
A pronoun and its antecedent must always agree in number; whether it is singular or plural. If the antecedent used is singular, then your pronoun should be singular too. If the antecedent is in plural form, the pronoun you use should also be in plural form. For example:
-The girls made themselves some sandwiches.
In this example, the antecedent used is "girls" which is in the plural form; therefore, the pronoun should agree to the antecedent and use the word "themselves".
