Which of the following is an arithmetic sequence?

Mathematics
2 answers:
NNADVOKAT [17]3 years ago

In order to find the answer, we have to find common difference for each.

Option 1.

first difference= 3-(-1) =4

second difference = -3-3=-6

here we dont have a fixed common difference, so its not an arithmetic series.

Option 2.

first difference= -2-2=-4

second difference = -6-(-2) = -4

third difference = -10-(-6) =-4

here we have a fixed common difference, so its an arithmetic series.

Option second is the correct answer

I'm completely lost help
e-lub [12.9K]
I can't see the line very well, but the initial value, also known as the y-intercept, is 1. I would tell you the rate of change but like I said I can't see the line very well, but count across from where the line touches the y axis until you can go up and hit a corner of a square on the grid and the line.. if that makes sense. I hope this helps!
