Answer:
an = 63(-1/3)^(n-1)
Step-by-step explanation:
This is a geometric sequence with first term 63 and common ratio -1/3.
The equation for the nth term is
an = 63(-1/3)^(n-1).
The equations standered form is y=-x^2/8-x/2-9/2
3/2 - x = -12
(multiply everything by 2 to get rid of fraction)
3-2x= -24
3+24 = 2x
3/2 + 12 = x
X=y=29 divided by square root of 2.
Hope this helped!!!
Sorry I could not give you the exact value.
I guess it is 20.506
