First find the formula which is A(N)=A+(N-1)D then fill in what you know
N=term your looking for
A=first term
D= common diffrence
Once filled in you will get this 18(18)=18+(18-1)-6
then solve to get 324= -84
Your final answer is that the 18th term is -84
Hope I could help
-64 + -4 = -68
That is because 64 + 4 = 68 and the negatives in this case are the same way as if it was all positive.
You plug in 2x + 4 into the y for the other equation (3x +y ) and solve for it
