Inductive Reasoning:  Arriving at conclusion based on specific examples or observations.  Given the premises, the conclusion is likely to be true but not certain.


Deductive Reasoning: 
Forming a conclusion that is based on general principles or axioms.  If the premises are true then the conclusion is guaranteed to follow.
