Use

#### Explanation:

FOR AN ARITHMETIC SEQUENCE:

"

"a" is the first term

"n" is the term number (eg. if you're looking for the 10th term, n = 10)

"d" is the difference between the terms

In you case,

d = -2

a = -2

So you would plug it in the formula accordingly,

Then use the distributive property,

And that's the recursive rule for your sequence.

NOTE: the formula given is only for arithmetic sequences, which is a sequence where the difference between the consecutive terms is constant.

Eg.
