Question

Hi everyone! I am posting a limit problem but need help. They say the answer is 1, but I keep getting -1 and need to understand why. Thanks! :o)

Answer 1

Seems to me that the second-to-last step should still have the factor of -1, but at the end you take the absolute value so it doesn't matter.

Answer 2

(-1)^(n-n-1) = (-1)^-1 = 1/-1 = -1 right? What on Earth am I missing? ugh

Answer 3

that's it! :o)
absolute value! that silly little absolute value is the culprit!
Thanks so much! I missed it! :o)
