In this paper, we study the following delay dynamic equation x Δ (t)+p(t)x(τ(t)) = 0f ort ∈ (t0,∞)T, where t0 ∈ T ,s upT = ∞, p ∈ Crd((t0,∞)T,R) alternates in sign infinitely many times and τ ∈ Crd((t0,∞)T,T) is a strictly increasing unbounded function satisfying τ(t) t for all t ∈ (t0,∞)T. Our results extend recent results for arbitrary time scales.
