Answer:
-8
Step-by-step explanation:
3/4x=-18+12
x=-6×4/3
x=-8
taking n = 5,
then A5 =



therefore, the fifth term is 2.
Let’s simplify!
y = 6(x - 2)² - 3
y = 6(x - 2)(x - 2) - 3
y = 6(x² - 2x - 2x + 4) - 3
y = 6(x² - 4x + 4) - 3
y = 6x² - 24x + 24 - 3
y = 6x² - 24x + 21
And so the music is really cheap!
