Answer:
2
Step-by-step explanation:
a1 = -128/27
a2 = 32/9
a3 = -8/3
Therefore, a = a1 = -128/27
r = a3 ÷ a2 = -8/3 ÷ 32/9 = -3/4
So 
Therefore, a4 = (-128/27) x (-3/4)^(4-1)
= (-128/27) x (-3/4)^3
= (-128/27) x (-27/64)
= 2
If this a table then the right side would be x and the left would be y. To find the y intercept you would have to find the zeroth term. (85 is the first term) i think the zeroth term might be 65. i subtracted 20 from 85 since that seems to be the pattern for y.
