Answer:
a^n=-9+(n-1).5
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=-9
n=?
d=+5
Arithmetic sequence=-9+(n-1)5
=-9+5n-5
Collect like terms
-9-5+5n
-14+5n
So the final answer is
an=-9+(n-1).5
Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
The first step is to simplify both sides
8+2x=x-6
Now you want to put all the xs on one side and the other like terms on the other side (Subtract both sides by x and subtract both sides by 8 so the x is alone on one side)
x= -14
