c'mon now, you should know this!

to start, what is the common difference between them all, that will help you realize if it is  arithmetic

anonymous · Answer

I tried to find it, But i think i was doing something wrong. @robz8

anonymous · Answer

Would the common difference be -2/3?

anonymous · Answer

okay, when i first look at this, i realize that all the fractions have a denominator of 3. that makes it easier for us to see the difference between them

12/3 - 10/3 == 2/3

10/3 - 8/3 == 2/3

8/3 - 5/3 == 2/3

anonymous · Answer

yes, that is the common difference!!

anonymous · Answer

Yay! So would I take away -2/3 from the last term I am given?

anonymous · Answer

Okay so Common difference is -2/3 and the next term is 2/3 @robz8
