Answer:
C. 3h - 6
Step-by-step explanation:
Sum of an infinite geometric sequence with the common ratio r, and the first term a1 is

we notice
-2 times -1/4=1/2,
1/2 times -1/4=-1/8
so a1=-2
r=-1/4 or -0.25
so the sum is

=

=

=

=
the sum is -8/5 or -1.6
Answer:
First one is a slope between 0 and 1
second one is a slope lower than 0
