consecutive odd integers.

x<0 and z>0 limits the range and the number line.

2 possible conditions:

1) -3 -1 0 1
2) -1 0 1 3

y could both be positive or negative.

possible product : PRODUCT of xyz. and range is based on product.

case 1) -3 * -1 * 1 =3

case 2) -1 *1*3 = -3.

Range :

3 - (-3) = 6.



E is the correct answer.

x < 0 and z > 0, and x, y z are consecutive odd integers i.e. they may be either {-3, -1, 1} or {-1, 1, 3}

Possible Values of xyz (Product of 3 values) = 3 and -3

Range = Highest - lowest = 3 - (-3) = 6

Answer: Option E

Keyword: If x, y, and z are consecutive odd integers and x < 0 and z > 0

z will be +ive, x will be -ive

There will be 2 such cases

-3 -1 1
-1 1 3

Range will be HT-LT = 1 + 3 = 4

I just hope xyz is not the product and is just a series of numbers, if that is the case then the range will be 6.

set of odd integers ; ( -3,-1,1) or ( -1,1,3)
xyz ; 3 & -3
so range
3+3 = 6
IMO E
