Multiply the number by 4. add 10 to the product. divide this sum by 2. subtract 5 from the quotient.
the first number is 1 and the result is 2
the second number is 5 and the result is 10
the third number is 9 and the result is 18
the fourth number is 10 and the result is 20
write a conjecture that relates the result of the process to the original number selected. part a)
represent the original number as n.
answer is 2n
part b represent the original number as n, and use deductive reasoning to prove the conjecture in part (a). multiply the number by 4.
with part b .
