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 list K?

A. 5
B. 6
C. 7
D. 11
E. 12

Range is defined as the difference between the largest & smallest number in a sequence (in ascending order). [spoiler]I am surely missing a concept, because in the above question I subtracted -4 from 7 & got 11 as the answer. The OA is 6 (7-1). What am I missing? Appreciate your responses.[/spoiler]

the question is asking the range for the postive numbers

least integer = -4

sequence = -4,-3,-2,-1,0,1,2,3,4,5,6,7

Range of positive integers = 7 -1 = 6

jep,

Remember Range is a interval between minimum and maximum.
