Let ##G## be a group of order ##2p## with p a prime and odd number.
a) We suppose ##G## as abelian. Show that ##G \simeq \mathbb{Z}/2p\mathbb{Z}##
Homework Equations
The Attempt at a Solution
Intuitively I see why but I would like some suggestion of what trajectory I could take to prove this.
I proved in an earlier problem that all groups with a prime order is a cyclic group.
I am sure it is a Sylow theorems problem.
Thanks!
