      Solution:

      Now putting n = 1, 2, 3, 4 we get,

      a1 = 6.1 + 2 = 8

      a2 = 6.2 + 2 = 14

      a3 = 6.3 + 2 = 20

      a4 = 6.4 + 2 = 26

      We can see that,

      a2 – a1 = 14 – (8) = 6

      a3 – a2 = 20 – (14) = 6

      a4 – a3 = 26 – (20) = 6

      Hence, the common difference is 6
