Hey there !!!!!
Dobereiner's law of triads states that when elements having similar properties are placed in increasing order of atomic weights in group of three,then atomic weight of middle element is arithmetic mean of other two elements.
Example: 1)Calcium,Strontium,Barium
2)Chlorine,Bromine,Iodine.
Hope this helped you !!!!!!!!

Answer:
ACCORDING TO DOBERNEIRS TRAIDS LAW THE ARTHEMATIC MEAN OF FIRST AND THIRD ELEMENT OF THE ATOMIC MASS IS EQUALS TO ATOMIC MASS OF SECOND ELEMENT
LIMITATIONS:
- All the elements couldn't be arranged at that time
- it also failed for very low or very high atomic mass like F,Cl,Br
- As the techniques improved for measuring atomic masses accurately the law was unable to remain strictly valid
