Tn = 6n + 2

On putting n = 1 we'll get the first term.

=> T1 = 6(1) + 2

=> T1 = 8

On putting n = 2 we'll get the second term

=> T2 = 6(2) + 2

=> T2 = 14

We know that, common difference is the difference between two consecutive terms.

Thus, common difference = T2 - T1 = 14 - 8 = 6

Thus, common difference is 6.
