Repeat the following procedure for the four given numbers. Multiply the number by 12. Add 6 to the product. Divide this sum by 2. Subtract 3 from the quotient. The 1st number is 1. The result is The 2nd number is 6. The result is The 3rd number is 9. The result is The 4th number is 10. The result is a. Write a conjecture that relates the result of the process to the original number selected. Represent the original number as n. The result is . (Simplify your answer.) b. Represent the original number as n, and use deductive reasoning to prove the conjecture in part (a). Multiply the number by 12. Add 6 to the product. Divide the sum by 2. (Simplify your answer.) Subtract 3 from the quotient
