Answer:
option A and E
Step-by-step explanation:
Arithmetic sequence converge, only in the case only when r=0
otherwise , arithmetic sequence goes increasing or decreasing at a constant rate.
So we ignore second and fourth option
If |r|<1 then geometric sequence converge
if |r|>1 then geometric sequence diverge
In option A, r= 1/5 that is less than 1 so it converge
In option C, r= -2 , |r| > 1 so geometric sequence diverge
In option E, r= 2/3 that is less than 1 so it converges
Answer is option A and E

Step-by-step explanation:
Answer: It's 48%. See below.
Step-by-step explanation:
By definition, percent means out of a hundred. For instance, 10 percent is 10 out of 100.
One way to make 
a percent is by making the denominator 100. In order to do so, multiply the numerator and the denominator by 4, since 25 times 4 is 100.
= 
= 48 %
This is very simple, and mental math is definitely possible. Hope this help.
