Abstract
In this paper, we first give a relation between the adjacency spectral radius and the $Q$-spectral radius of a graph. Then using this result, we further give some new sharp upper bounds on the adjacency spectral radius of a graph in terms of degrees and the average 2-degrees of vertices. Some known results are also obtained.
