Your mom.

OpenStudy (anonymous):

you want to take a guess? :P

OpenStudy (anonymous):

We're looking for three integers, so let's let n be the first integer.

OpenStudy (anonymous):

I'll say b, In my opinion.

OpenStudy (anonymous):

Wait that's not right.

OpenStudy (anonymous):

What integer comes after n?

OpenStudy (anonymous):

idk i was guessing it was d

OpenStudy (anonymous):

Why d?

OpenStudy (anonymous):

looking at it to me it was the best answer

OpenStudy (anonymous):

Yes, but why?

OpenStudy (anonymous):

i really dont know i was guessing

OpenStudy (anonymous):

You could have been a little more accurate with your guess :P Indeed, the numbers in d add up to -27... but are they consecutive? XD

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Do you know what consecutive means? :>

OpenStudy (anonymous):

uhh... they follow one another.

OpenStudy (anonymous):

thanks i cant think right now and i didnt know

OpenStudy (anonymous):

So... what's your new guess? Bit of a heads-up... you get this one wrong again, you're on your own :P I'm not a fan of guessing... so make this one count. I'll *tell* you if you got it right ^^

OpenStudy (anonymous):

Is that you?

OpenStudy (anonymous):

i am thinking its C i just added it up on my phone

OpenStudy (anonymous):

It's correct. Notice that they ARE indeed, consecutive here... -8, -9, -10, they follow one another. Good guess. Don't make a habit of it :P
