Question

Determine if the following Serie converges or not

\[\sum_{k\in \mathbb{N}}2^{2-k}\]

is the solution : yes its convergence and convergt against 8 ?

Answer 1

\[\sum_{k \in \mathbb{N}}2^{2-k}=4\sum_{k \in \mathbb{N}}\frac{ 1 }{ 2^k }=4\cdot 2 = 8\]

Answer 2

that means the solution right sure? thank you very much pgpilot

Answer 3

it converge right?

Answer 4

yeah

Answer 5

ok thank you

Answer 6
