2.) A.) Find the next item in the pattern. 1, 2, 3, 5, 8, 13, . . .
B.) Describe the pattern in words.
3.) Is the statement below true or false? If it is false give a counterexample to justify the conclusion.
The difference of two odd numbers is a prime number.
4.) Identify the hypothesis and conclusion of the statement
“If an angle has a measure less than 90, then the angle is acute.”
A.) Hypothesis
B.) Conclusion
For numbers 5-7 state whether the conjecture is valid or invalid with the given information. If it is valid
state whether it is by the Law of Detachment or the Law of Syllogism .
5.) Given: If a ray bisects an angle, two congruent angles are formed.

YW bisects XYZ.
Conjecture: XYW  WYZ

6.) Given: If a number is a prime number, then it is an odd number. If a number is not divisible
by 2, then it is an odd number. Conjecture: If a number is not divisible by 2, then it is a
prime number.

7.) Given: If a whole number ends in 0, then it is divisible by 2. If a whole number is divisible by 2, then it is
even. Conjecture: If a whole number ends in 0, then it is an even number.
