6

Explanation:

The common difference in an arithmetic progression is the difference between successive terms in a sequence.

This term when added to the preceding one results in the subsequent figures in the sequence.

 To find the common difference, subtract the second term from the first one.

First term = 2

 Second term  = 8

 Common difference  = Second term - first term = 8 - 2  = 6

Third term = 14

   Common difference  = 14 - 8  = 6
