Let A and K be positive integers and є ∈ {−2;−1, 1, 2}. The main contribution of the paper is a proof that each of the D(є2)-triples {K,A2K + 2єA, (A + 1)2K + 2є(A + 1)} has unique extension to a D(є2)- quadruple. This is used to slightly strengthen the conditions required for the existence of a D(1)-quintuple whose smallest three elements form a regular triple.
