+981 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
