a_{n}=4\left(-5\right)^{1-1}
Consider the first equation. Insert the known values of variables into the equation.
a_{n}=4\left(-5\right)^{0}
Subtract 1 from 1 to get 0.
a_{n}=4\times 1
Calculate -5 to the power of 0 and get 1.
a_{n}=4
Multiply 4 and 1 to get 4.
a_{n}=4 n=1
The system is now solved.
