Explanation:

A generalization is a process in which one statement or specific case is taken to a broader context that leads to the creation of general statements that can be applied to a complete population or group of cases. This implies when you generalize you state something always happens or is true in all cases, due to this it is common generalization is not valid, as there are cases that might differ from the general statement. In the case of "Math is challenging subject for many students", the idea of some students having problems with Math was generalized to many students finding Math challenging, due to this, this is a generalization statement. However, it does not state this is the situation of all students and thus, particular cases are allowed to be different, which makes it valid as it does not state one hundred percent of the students find Math challenging because there are always particular cases.
