This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = and r = 10 , thus
=

Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x = , which in this case is
.
Then plug that x value into the equation to get the y coordinate:
4(-1)²+8(-1)-8 = -12
