Question

Σ(x-5)^n /n.5^n
interval of convergence?

Answer 1

Is this \[\sum \frac{(x-5)^n}{n(0.5)^2}\]

Answer 2

\[\sum_{∞}^{1} ( (x-5)^n) \div n \times5^n \]

Answer 3

that is a complicated series, but what I think is that the terms are increasing and therefore there is no solution.
CORRECT ME IF I AM WRONG PLEASE!

Answer 4

you can check what I said, by just normally plugging in values for n, just plug ion 1, 2,3 and 4.

Answer 5

solution exists

Answer 6

How can I figure this out with an x in it?

Answer 7

because it is a power function

Answer 8

it depends on the x, if x is 5 or more than there is no solution.

Answer 9

I am really not sure about this, tag me when you get it, OK?

Answer 10

ok

Answer 11
