What is the 11th term of the geometric sequence 178, 106.8, 64.08, ...? A

0.39

B

0.65

С

1.08

D

1.79

Step-by-step explanation:

step 1. A geometric sequence is found by multiplying subsequent term by a number r.

step 2. 106.8/178 = 0.6. 64.08/106.8 = 0.6. a = 0.6. note that a geometric series must have the same number when dividing successive terms.

step 3. an = ar^(n - 1) = a(0.6)^(n - 1)

step 4. given a1 = 178. an = 178(0.6)^(n - 1)

step 5. therefore a11 is the 11th term!

step 6. a11 = 178(0.6)^10 = 1.0763 = 1.08.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
