A.
n=1 is -4*1=-4
1st term is -4
2nd is -4/3
3rd is -4/9
4th is -4/27
b. converge because -1<r<1
c. as long as -1<r<1, then
the sum of the infnite series is
a1=-4
r=1/3
=
=-12/2=-6
it has a sum of -6
sum of gemoetric sequence is
a1=6
r=2
n=10

5*(3+4+5+6+7+8)=
165
answer is 4th one
Answer:
The last choice: x = 3.
Step-by-step explanation:
M < WYX = 1/2 * 78 = 39 degrees ( angle opposite te arc of 78 degrees).
Therefore m < XWY = 180-114-39 = 27 degrees.
7x + 6 = 27
7x = 21
x = 3.
