In the plane rectangular coordinate system, translate the point P (M + 2, 2m + 4) to the right by 1 unit length to get the point P '(4, 6), then the value of M is______ ．
∵ point P (M + 2, 2m + 4), ∵ right translation 1 unit length can get p '(M + 2 + 1, 2m + 4), ∵ p' (4, 6), ∵ m + 2 + 1 = 4, 2m + 4 = 6, the solution is: M = 1, so the answer is: 1
