Question 161818This question is from textbook Algebra 1
: Please can you help me with Arithmetic Sequences because I don't know how to
do it. The problem say determine whether each sequence is an arithmetic
sequence. If it is, state the common difference.
The problem is -15,-11,-7,-3,....
Thanks for your help because I don't get how to do it so if you help me out to
were I can do it on my own then thanks a lot.It's on page 236 my teacher wants
me to do all the even numbers on the practice and apply.

a sequence is arithmetic if there is a COMMON difference
__ if the difference between all the pairs of consecutive (next to each other) numbers is the same

-15+4=-11
-11+4=-7
-7+4=-3

the common difference is 4
