comment Prove that the only numbers not expressible as a sum of consecutive positive integers takes the form $2^n$ for some $n \in \mathbb N$
Fixed thanks @MarkBennet. Could you elaborate on why writing this odd factor as a sum of consecutive integers helps me? As in the comment below I'm having trouble seeing where this gets me.

Sorry, I'm not sure I understand why writing $x = (m+(m+1)) \cdot 2^\alpha$ (if $x$ has one odd factor) helps me...

comment Buy more lottery tickets or more multipliers?
Actually I double with chance $1$ in $2$ so isn't it ($1/2 \cdot 2 + 1/3 \cdot 3 + \cdots$)? But thank you this is the way I was thinking about it
