When a carbocation forms in the an E1 reaction, the product determining step is the second deprotonation to form the alkene. You can think of the transition state for this as one in which there is a partial double bond between 2 carbon atoms. Since it’s a partial double bond, you receive the same stabilizing effect,

This is saytzeff rule. Hence, 2-Bromopentane gives Pent-2-ene as the major product. The second carbon from right is alpha carbon while 1st and 3rd is beta carbon. 3rd carbon is attached with other ethyl group (C-4 ), so hydrogen is removed from this to get alkene according to above said rule.

Zaitsev’s rule (sometimes spelled "Saytzeff") states that in an elimination reaction, when multiple products are possible, the most stable alkene is the major product. That is to say, the most highly substituted alkene (the alkene with the most non-hydrogen substituents) is the major product.
