Question
1. Use deductive reasoning to show that the following procedures
produce a number that is one less than twice the original number.
Procedure: Pick a number. Multiply the number by 4, add 8 to the
product, divide the sum by 2, and subtract 5.
2. Use inductive reasoning to predict the next number in each of the
lists.
a. -2, 0, 2, 4, 6, 8, -
b. 1, 2, 5, 10, 17,
C. 2, 5, 10, 17, 26,
3. Verify that the statement is incorrect by giving a counterexample.
a. x| 2 5
