A syllogistic fallacy is more of a generalization than it is a sequence or analogy. This error of reasoning occurs by first mentioning something broad/general then proceeds to make a conclusion about something that is very specific by means of generalizing. For example, this would be considered fallacy of syllogism:
All jets are air crafts. All propeller airplanes are air crafts. Therefore, propeller airplanes are jets.
Thus, you can see how a generalization is made about propeller airplanes being jets because they are both air crafts.
