Question

after using the ratio test to determine by interval convergence this is what i got, so what is my interval convergence 1-2x<1

Answer 1

solve for x
\[1-2x<1\]
\[-2x<0\]
\[x>0\] but i will be willing to bet this is wrong because it does not look like a radius of convergence to me. what was the series?

Answer 2

actually its suppose to be written the other way around 2x-1<1

Answer 3

then x < 1

Answer 4

and the 2x-1 is in absolute vale

Answer 5

so you would get 0<x<1
