Answer:

The most likely solution sought is 13:

Beginning with 3: subtract 9, add 18, subtract 8, add 16, subtract 7, add 14, etc. Each time, reduce the number subtracted by one, and double that number to add.

So, beginning with 3: 3-9 = -6, -6+2(9) = 12, 12-8 = 4, 4+2(8) = 20, 20-7 = 13, etc.

3, -6, 12, 4, 20, 11, 30

Explantion:

the difference between 3 and -6 is 9 same as 12 and 4 so you are going to take 9 away from 20 then you should end up will 11

the difference between -6 and 12 is 19 same as 4 and 20 so you are going to add 19 to 11 and you should get 30

I hope I answered your question, it should all be correct but if not please let me know

3. ms. Johnson placed two different orders with TR's special item store. each order was for 40 jars with the circus logo imprint

1.The height is 6 inches ad the width (diameter) is 3 inches!
2. So the jars are Volume ≈ 42.41 inches so each boy needs 200 / 42.41 which equals approximately 4.72 inches per jar. So if wach boys have half the amount of jars which is 20 you multiply 20 by 4.72 which is 94.4 inches for each boy!
