Here is a rule that can be used to build a sequence of numbers once a starting number is chosen: Each number is two times three less than the previous number. 1.Starting with the number 0, build a sequence of 5 numbers.
2.Starting with the number 3, build a sequence of 5 numbers.
3.Can you choose a starting point so that the first 5 numbers in your sequence are all positive? Explain your reasoning.
