Reasoning
See how to find inductive/deductive reasoning.
4 examples and their solutions.
Inductive Reasoning
Definition
Specific Examples
↓ Pattern
General Conclusion
Inductive reasoning is a reasoning↓ Pattern
General Conclusion
that starts from [specific examples]
to get a [general conclusion],
usually by finding a pattern
from the specific examples.
Example
1, 3, 5, 7, ?
Solution 1 + 2 = 3
3 + 2 = 5
5 + 2 = 7
7 + 2 = 9
Pattern: ( o )
So finding ? is inductive reasoning.
3 + 2 = 5
5 + 2 = 7
7 + 2 = 9
Pattern: ( o )
So finding ? is inductive reasoning.

Example
He went there yesterday.
He goes there today.
So he will go there tomorrow.
Inductive reasoning?
Solution He goes there today.
So he will go there tomorrow.
Inductive reasoning?
He went there yesterday.
He goes there today.
So he will go there tomorrow.
Pattern: ( o )
→ Inductive Reasoning
He goes there today.
So he will go there tomorrow.
Pattern: ( o )
→ Inductive Reasoning

Deductive Reasoning
Definition
Known Statements
↓ Logic
Specific Conclusion
Deductive reasoning is a reasoning↓ Logic
Specific Conclusion
that starts from [given & known statements]
to get a [specific conclusion],
usually by using logic.
Example
If it's raining, then I'm staying home.
If I'm staying home, then I'm listening to music.
So if it's raining, then I'm listening to music.
Deductive reasoning?
Solution If I'm staying home, then I'm listening to music.
So if it's raining, then I'm listening to music.
Deductive reasoning?
pq
If it's raining, then I'm staying home.
qr
If I'm staying home, then I'm listening to music.
