What is the next term of the geometric sequence?<br> -128/27,32/9,-8/3
IrinaVladis [17]

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 a_n=ar^{n-1}=-\frac{128}{27} (-\frac{3}{4})^{n-1}

Therefore, a4 = (-128/27) x (-3/4)^(4-1)

= (-128/27) x (-3/4)^3

= (-128/27) x (-27/64)

= 2

How do I find the y-intercept of this? : <br><br> 2 85<br> 6 105<br> 9 120<br> 14 145<br> 18 165
chubhunter [2.5K]
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.
