What is the system? (Is there supposed to be an image?)
You can’t really answer this without showing us the the answer you got from item 6
(3n)-2=5
Move all numbers without a variable to the right side of the equation
3n=7
Divide 7 by 3
n=2.333
We are given with the function summation of 16*(5) ^(I-1) from 1 to infinity. As we assume in the calculator that infinity is equal to a very large number, the result that can be obtained is undefined. This means the number is very large. This is because the ratio (15) is large too. The series is divergent since the number in the infinite geometric series is ever increasing. Answer is B.
