Well I hope I don't get my arithmetic wrong.. For question 21, the answer should be B not A.

16/9=4/3... since 4/3 x 4/3 =16/9. You have to simplify it don't you?

i'm pretty sure that the expression for the sum of a geometric series is a/(1-r), not r/(a-r)

For # 20, isn't a geometric series from 1 to infinity supposed to have the power (n-1)?

Also for problem 24, 0 plugged into (-1/x) is not 0, making the final answer -e^3-(-infinity) which equals just infinity.

For question 25, the bound is undefined at -2 as well, so answer c is just as valid as answer a which are both invalid by your logic...

For problem 22, the denominator is not factorable. I think there might be a typo, should probably be x^2 + 4x -5
