Need the answer thanks!

The sum does not exist, but if you are in a senior math class, it could be - infinity.

Step-by-step explanation:

If the sum does not have an endpoint (and it looks like it does not), then the sum really does not exist.

Consider this question.

Does the sum stop at 0 as in

50 + 40 + 32  + 24 + 16  + 8 + 0

But why not - 8 or - 16 or ...

So it is not that the sum does not exit. It is that we do not know where that stop is. Depending on your grade level, you could answer - infinity, but I doubt that is the expected answer.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
