tell whether the sequence is arithmetic. If it is, what is the common difference? -12, -7, -2, 3, ...

Answer:
Yes, 5
Step-by-step explanation:
We see a difference in every single number as we go to the right. We see that [tex]-7 = -12 + 5[/tex], [tex]-7 = -2 + 5[/tex], etc. So, the common difference is [tex]\boxed{5}[/tex].
