Abstract: Let $ x$ be a real irrational number and $ p_n/q_n, \,\,n=0,1,2,\ldots $ its sequence of continued fraction convergents. Define $ \theta _n=q_n\big \vert q_nx-p_n\big \vert.$ For almost all $ x$ the distribution function of the sequence $ \big \vert\theta _{n+1}-\theta _{n-1}\big \vert, \,\,n=0,1,2,\ldots $ is determined and its expectation calculated.
