What is the common first difference of this arithmetic sequence? 77, 65, 53, 41, 29

OpenStudy (solomonzelman):

your question at the beginning makes no sense (to me at least).

OpenStudy (solomonzelman):

If it is common then why first, and it first why common..... don't we know that in an arithmetic sequence the difference is always the same?

OpenStudy (solomonzelman):

Well, I guess your answer should be just the general common difference of this sequence.

OpenStudy (solomonzelman):

Can you find the difference, or need help doing that?

OpenStudy (anonymous):

i got it

OpenStudy (solomonzelman):

yes, can you tell me what you go, so that I can verify your answer?
