Question

What is an arithmetic sequence with a common difference of -5?

Answer 1

`5,0,-5,-10...`

Explanation:

in an arithmetic sequence, the common difference `(d)` is constant.

to get from one term to the next, the process is always to add `d`.

if `d = -5`, `-5` is added to find the next number in the sequence. this is the same as subtracting `5`.

`5,0,-5,-10...`
`5 + (-5) =0`
`0 + (-5) = -5`
`-5 + (-5) = -10`
