#1**+2 **

Hey Hev!

When n = 1,

\(4(-5)^{1-1}=4(-5)^0=4\cdot1=4\)

When n = 2,

\(4(-5)^{2-1}=4(-5)^1=4\cdot-5=-20\)

When n = 3,

\(4(-5)^{3-1}=4(-5)^2=4\cdot25=100\)

We can tell there is a pattern with multiplying by -5.

The next three terms in order are -500, 2500, and -12500

You add them to find the solution,

I hope this helped,

Gavin
