“Our character is basically a composite of our habits. Because they are consistent, often unconscious patterns, they constantly, daily,
express our character…”
-Stephen R. Covey
Inductive Reasoning
Inductive reasoning is reasoning based on patterns you observe.
Examples:Find the pattern of the sequence and show the next two terms or symbols.
2, 4, 8, 16, …
1, 3, 7, 13, 21, …
Using Inductive Reasoning
A conjecture is a conclusion you reach using inductive reasoning.
Example:Sum of odd numbers.
11 + 31 + 3 + 51 + 3 + 5 + 7
= 1= 4= 9= 16
= 12
= 22
= 32
= 42

Using Inductive Reasoning
A conjecture is a conclusion you reach using inductive reasoning.
Example:Sum of even numbers.
22 + 42 + 4 + 62 + 4 + 6 + 8
= 2= 6= 12= 20
= 1(1 +1)= 2(2+1)= 3(3+1)= 4(4+1)

Using Inductive Reasoning
A counterexample to a conjecture is an example where the conjecture does not work.
Example:Find a counterexample to the statements.
“If a number is divisible by 2, then it is also divisible by 6.”
“You can connect any three points to form a triangle.”
