Question

Write your answer using decimals and integers

Answer 1

-1 and 4

Explanation:

The formula is
`a_(n) = a_(1)(r)^(n-1)`

The first blank is
`a_(1)` which is the first term, -1

The second blank is r which is the common ratio, 4.

TIP: if the rule of the sequence was to divide by 4, then the common ratio would be 1/4.

`a_(n) = -1(4)^(n-1)`

Hope this helps!
