Problem 7:

Each successive number is "two times three less"   means  "six less"    

 

So 

 

1.   0 , 6, -12 , -18 , -24

 

Can you do the other two, GM, knowing this  ????

 

[ Hint for number 3.....start with  an integer > 24 ]

Answer:

1. 0, -6, -12, -18, -24, -30      Common difference: d = -6

2. 3, -3, -9, -15, -21, -27

3. 30, 24, 18, 12, 6, 0

You can choose a starting point so that the first 5 numbers in your sequence are all positive just by choosing a integer greater than 24 just enough for positive numbers in the continuing squence.
