Is this sequence possible?

Term 6 is 71
Term 18 is 29

Find the equation

It's an arthimetic (sp) sequence meaning it only adds or subtracts.

This was on a test today, and I spent about 30 minutes, couldn't figure it out.

BTW it has to be a whole number or fraction in the equation, you cannot use decimals (We weren't allowed calculators.)

I want to see if it was possible or not, because that cost me 5 points >_<

make it a fraction

6 = 71
18= 27

pull out gcfs mess with ratios if i wwas a better person id do it for you

92 - 7/2x

[Blazestorm]

X being the term correct?

Damnit... it works

Ah well, good job, I guess I needed to spend more time on it

[MayAMonkeyBeYourPinata]

Yup

[Rumble]

woah, we just did this stuff a few days ago in math class! are you in grade 11?

[Blazestorm]

10th haha

But I'm in 11th grade math...

And I'm in physics... I'm the ONLY sophmore in the class... EVERYONE else is a junior or senior, mostly seniors...

92 - 7/2x

man, it's been forever since i've had to figure these out, could you "show your work"? I can't figure out how you got it and it's killing me

18x-6x = 71-29
X = 3.5
6(3.5) = 71 + Y Y= term 1 minus 71

I'm pretty sure thats about it,

ok, I got it now. thanks. I wasn't understanding you're 92-7/2x. I was thinking 92-7(over) 2x.
