when we say even numbers, Can we consider negative numbers too?
same question regarding multiples. can we consider negative numbers as multiples of a positive number?
I used to think "NO" as the answer to both the questions and then I saw this:
What is the sum of the numbers in a list of m even integers?
(1) The largest integer on the list is 12.
(2) The list consists of 6 consecutive multiples of 4.
and the OA is C
a basic question

I also used to think that even numbers or odd numbers are only positive. But when I attended my GMAT class, first thing that my GMAT instructor told me that in GMAT, even numbers or odd numbers could be both +ve and -ve. The key word in the question below is "integer" hence even number can be both +ve or -ve.
Regarding your second question, I guess yes -ve no. can be considered as multiple of +ve no. as long as it has another -ve factor also.
Regarding the question, sum of m even "integers" can be obtained by both statements as -8 + -4 + 0 + 4 + 8 + 12 = 12.
Hence, C is the answer.
