<P> The remaining seats are allocated one at a time, to the state with the highest priority number . Thus, the 51st seat would go to the most populous state (currently California). The priority number is determined by a formula that is mathematically computed to be the ratio of the state population to the geometric mean of the number of seats it currently holds in the assignment process, n (initially 1), and the number of seats it would hold if the seat were assigned to it, n + 1 . </P> <P> The formula for determining the priority of a state to be apportioned the next available seat defined by the method of equal proportions is </P> <Dl> <Dd> A n = P n (n + 1) (\ displaystyle A_ (n) = (\ frac (P) (\ sqrt (n (n + 1))))) </Dd> </Dl> <Dd> A n = P n (n + 1) (\ displaystyle A_ (n) = (\ frac (P) (\ sqrt (n (n + 1))))) </Dd>
