If I understand the question correctly.The answer cannot be an odd number, since the sum of even numbers cannot deliver a odd number, even if number of even numbers summed was odd. 2+4+6=6+6=12 So the answer could only be 256 or 258.
Well, the question is asking for all the possible values of n (to be more precise, their sum), while you seem to understand it as the sum of first n positive integers.
The question is asking for the possible values of n. The question is asking for the first n positive integers. It could be asking for the first 5 positive even integers, and they would be 2, 4, 6, 8, and 10. While even integers will always add up to an even number, it is asking for the number of even integers. This number does not always have to be even.
The question is also asking for the sum of possible values of n. This doesn't necessarily have to be even since as I said before, the number of even integers can be any number. In the first comment of yours, you put: 2+4+6=6+6=12. There are 3 starting even integers, and this number is odd.
@flareashes Plain old TV. Magic fingers. (And a touch-screen overlay.)
@PokemonSucks7 No, I'm pretty sure it's 847...
What type of board is that?
@PokemonSucks7 That's 1-4(212-m^2) = 4m^2 - 847.... There's more in that discriminant than just 4(212-m^2)!
@ArtofProblemSolving 4(212-M^2)=848-4M^2 since 212*4=848
AWESOME!
@ArtofProblemSolving he did the 1- afterwards again
he probably has a secret way to write on the board
use the known formula for the sum of an arithmetic ... For those that this is simpler to figure m*m etc...
@ArtofProblemSolving well he 1-c which c =4(212-m^2) later on
4×212 =848 not 847.
he got -848 and u add +1 to get -847
wow you got into mop!!

However, the n numbers must be even integers. The sum of even integers is always even.

@@camelliaguan6388 so what abt (m square ) why didn't he use directly m ??
he messed up bad
it's not 847 its 848
no u
