Answer: Ca, Sr, and Ba is one of Dobereiner's triads. Here, atomic masses of Ca, Sr, and Ba are 40, 88, and 137 respectively. The atomic mass of Sr that is 88 is almost the mean of atomic masses of Ca and Ba.                                                                        

The atomic mass of a middle element in dobernier Sr = 40+137/2=88.5
