Gustavo and yuki were asked to find an explicit formula for the sequence 19, 0, -19, -38...

KiRa [710]

Answer:

<h2>Neither Gustavo nor Yuki</h2>

Step-by-step explanation:

It's an arithmetic sequence.

$0-19=-19\\-19-0=-19\\-38-(-19)=-38+19=-19$

The difference is constant.

The explicit formula of an arithmetic sequence:

$a_n=a_1+(n-1)d$

Substitute:

$a_1=19,\ d=-19$

$a_n=19+(n-1)(-19)$ <em>use distributive property</em>

$a_n=19-19n+19\\\\a_n=(19+19)-19n\\\\a_n=38-19n$
