Deductive reasoning means...

• Guessing

• Ura nok seblu!

• Testing and observing patterns to make conjectures

• Making general observations of facts, theorems and applying them to specific situations.

IF 3...6...9...12...
AND 24...27...30...?
THEN the next term is going to be 33

• Inductive
• Deductive

What is the midpoint of the line segment shown?

Remember to write your answer as a point. Do NOT use spaces between characters. Write your answer as a decimal. Just write the answer...no need for a complete sentence.

What is the length of the line segment shown?

Write your answer as a decimal, rounded to the nearest hundredth. Just write the answer...no need for a complete sentence.
