Question

For the following arithmetic sequence: determine the common difference. Find the next three terms of the sequence.

e) 2/3 , 1/15, -8/15

I really don't get how to solve this one, I see no pattern :\

Answer 1

I do believe that all the denominators need to be the same to see the pattern. 2/3 is the same as 10/15 so the pattern looks like 10/15, 1/15, -8/15. Subtracting 9 from the top set of #'s

Answer 2

Oh I get it now. Thanks soo much Jess :)
