Question

How do you find the arithmetic means for the sequence `-8, __, __, __, -24`?

Answer 1

`-4` is being added after each term to get the next term in the sequence.

Explanation:

"Arithmetic means" means that a constant number is being added again and again to create a sequence.

Let "the number" = n

We know that `n` is negative because the numbers in the sequence are getting more negative.

`n=((-24)-(-8))/4`
(The denominator of 4 comes from the 4 times a number has to be added)

`n=(-16)/4`

`n=-4`
