Inductive Reasoning
• Inductive Reasoning: a type of reasoning in which the conclusion is based on several past observations
• Ex:– 2, 5, 8, 11, 14, ___, ___– We have had pop quizzes on Friday for the
past four weeks…• Using inductive reasoning you would conclude that
we would likely have a quiz every Friday.

Deductive Reasoning
• Deductive Reasoning: a type of reasoning in which the conclusion is based on accepted statements.
• We used deductive reasoning to come up with the formula for the Distance Formula.
• Pythagorean Theorem

Conditional Statement(“If-then” statements)
• If it’s raining, then the game is canceled.– If p, then q.
• Hypothesis = it’s raining (“the condition”)
• Conclusion = the game is canceled.
![Page 7: Warm-up: What is the next term in the sequence? 1)3, 5, 11, 21, 35, ___ 2)](https://reader036.fdocuments.us/reader036/viewer/2022081822/56649e8f5503460f94b93c6f/html5/thumbnails/7.jpg)
Notation
If it’s raining, then the game is canceled.
Hypothesis = p = it’s raining
Conclusion= q = the game canceled
~p = (“not p”) it is NOT raining.
~q = (“not q”) the game is NOT canceled.
= implies
![Page 8: Warm-up: What is the next term in the sequence? 1)3, 5, 11, 21, 35, ___ 2)](https://reader036.fdocuments.us/reader036/viewer/2022081822/56649e8f5503460f94b93c6f/html5/thumbnails/8.jpg)
The Converse of a Conditional Statement
• If it’s raining, then the game is canceled.– If p, then q.
• If the game is canceled, then it’s raining.– If q, then p.
• The hypothesis and the conclusion are interchanged.
![Page 9: Warm-up: What is the next term in the sequence? 1)3, 5, 11, 21, 35, ___ 2)](https://reader036.fdocuments.us/reader036/viewer/2022081822/56649e8f5503460f94b93c6f/html5/thumbnails/9.jpg)
The Inverse of a Conditional Statement
• If it’s raining, then the game is canceled.– If p, then q.
• If it’s NOT raining, then the game is NOT canceled.– If not p, then not q.
• The hypothesis and the conclusion are negated.
![Page 10: Warm-up: What is the next term in the sequence? 1)3, 5, 11, 21, 35, ___ 2)](https://reader036.fdocuments.us/reader036/viewer/2022081822/56649e8f5503460f94b93c6f/html5/thumbnails/10.jpg)
The Contrapositive of a Conditional Statement
• If it’s raining, then the game is canceled.– If p, then q.
• If the game is NOT canceled, then it’s NOT raining.– If not q, then not p.
• The hypothesis and the conclusion are interchanged and negated.
