Let p be an odd prime number. For n £ {1,...,p - 1} we denote the inverse of n modulo p by n* with n* ∈ {1,...,p - 1}. Given e > 0, we prove that in any range n ∈ {N + 1,..., N + L} C {1,...,p - 1} of length L > p 1/2+e the probability that n* has the same parity as n tends to 1/2 as p -> +∞. This result was previously known only to hold true in the full range n ∈ {1,...,p-1} of length L = p - 1. We will also obtain quantitative results on the pseudorandomness of the sequence (-1) n+n* for which we estimate the well-distribution W and correlation measures C k as defined by Mauduit and Sarkozy (1997).
