Selah · Answer 1

Yes, here is how we know.

First subtract the first two terms.

4 - ( - 1) = 5

Then compare it when you subtract the next pair

-1 - (-6) = 5

Then the next

-6 - (-11) = 5

And lastly

-11 - (-16) = 5

Darian · Answer 2

Yes, it is an arithmetic sequence. The common difference is - 5. Each term has been discovered by subtracting 5 from the previous.
