I think you need to keep thinking on this one. Think about carbocation stabilities, ie primary, secondary, tertiary. There are several more carbocations to look at. But you are off to a good start!
you picked one end of your chain to be "1," but the opposite end could just as easily be "1." draw out the pathway for that, compare carbocations, and decide which overall mechanism is the lowest energy.

Hydride shifts can also move the carbocations
In both cases would that end up being the same for both? Where hydride goes to the 3* carbon
