I believe that 7/45 is a repeating decimal
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
I think is the second choice!!!

Answer:
18.027756
Step-by-step explanation:
Pythagorean Theorem
10²+15²=c²
100+225=c²
325=c²
√325=c
c=18.027756
