Title: What is the common difference of this arithmetic sequence? Post by: juju2744 on Feb 19, 2013 What is the common difference (what you add to continue the pattern) of this sequence?
5, -10, 15, -20,... Ok so no common difference got it. My hw question asks me to find a formula for the nth term of this sequence. How do I do that? Title: What is the common difference of this arithmetic sequence? Post by: JUJUBEEM on Feb 19, 2013 25, -30, 35, -40, and so on...
Title: What is the common difference of this arithmetic sequence? Post by: michaelnice on Feb 19, 2013 The difference between sequential terms is
-15, 25, -35 There is no common difference. Common differences exist in arithmetic sequences. This is not an arithmetic sequence. |
