Bunnel , I didn't understand when the largest positive integer in the list is 7 , how did the range become 7-1 = 6 , shouldn't it be 7

Solution:

Set K = ( -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7)
Range is defined as the highest value of f(x) and the lowest value of f(x). Over here the range will be 7 - (-4) = 11.

Try making a graph of the set K and see what is the difference between the maximum value and the minimum value.


The set is {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}. The question asks to find the range of the POSITIVE integers in the list.

The range of the POSITIVE integers in the list is {largest} - {smallest} = 7 - 1 = 6.

Hope it's clear.

Since -4 is the least integer in list K, then 7 is the largest integer in that list. Thus the range of the positive integers in the list is 7-1=6.

Answer: B.

Simple one. However, the only thing to notice in this question is "range of the positive integers". You miss this and you are gone :P

Answer Options:

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


numbers are -4,-3,-2,-1,0,1,2,3,4,5,6,7

range of positive numbers = 7-1= 6

note: zero is neither positive nor negative. it is neutral.

so if it asks you for the positive and negative range then it would be 11 right? 7- (-4)= 11? or do you get two answers one for positive and one for negative?

The set is {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}.

The range of the POSITIVE integers in the list is {largest} - {smallest} = 7 - 1 = 6.
The range of the NEGATIVE integers in the list is {largest} - {smallest} = -1 - (-4) = 3.

The range of the whole set is {largest} - {smallest} = 7 - (-4) = 11.

Is not this an arithmetic progression with common difference as 1?

nth term in given by \(a_n\) = \(a_1\) + (n-1) d
We are given that \(a_1\)= -4 and hence we can solve for a_12 and n=12

Perfectly valid approach!

This is so cheeky from GMAT.

The question asks what is the range of positive integers, not the range of the set.
so, answer is 7-1 = 6 not 7-(-4)=11

Range in a set is defined as difference between maximum and minimum.
Maximum +ve = 7
Minimum +ve = 1
Range = 7 - 1 = 6.

Also, some people do mistake in counting numbers.
In this case, 12 numbers include -4 , so the maximum number will be (-4 +12 ) -1 = 7
