In this paper, we study almost Ricci-Yamabe soliton of (α, β)-type which admitting concurrent-recurrent vector field. We show that if the potential vector field is (i) conformal vector field, or (ii) pointwise collinear to the concurrent-recurrent vector field, or (iii) gradient of a smooth function, then the soliton is Einstein or almost β-Yamabe soliton. At the end of this paper, we give explicitly some manifolds which admit (or do not admit) concurrent-recurrent vector field.
