Problem Solving

List k consists of 12 consecutive integers. If -4 is the least integer in list k, what is the range of the positive integers in likest k?
5
6
7
11
12

Thanks

Since -4 is the least number in the list, the list will look like this -
-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7.

The least positive number in the list is 1
The highest positive number in the list is 7.
Range of the positive integers = The highest positive number in the list - The least positive number in the list = 7 - 1 = 6

IMO B

-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, >>>12 consecutive integers Range = 7-1 = 6 so B

Correct me please, if I am wrong

Yes... both of you are correct. I figured it out after the practice test. Easy question. My mistake was 7-(-4) = 11.. stupid me..
