To find the missing number in each data set you must look for any patterns that are included in the data set. Here are some examples:
A data set that goes by 2's:
2,4,6,_,10,12. In this case you would need to go by 2's to figure out the missing number.
A data set that goes by 5's:
5,10,15,_,25,30. In this case you would need to go by 5's to figure out the missing number.
I hope this helped you and that you understand how to find the missing number better. Good Luck!!
