Correct Answer: Option B

Explanation

T\(_n\) = a + (n - 1)d

T\(_4\) = a + 3d = 16 - - - - - - - - - - - - - - (i)

T\(_8\) = a + 7d = 40 - - - - - - - - - - - - - - -(ii)

Solving simultaneously using the elimination method(subtract eqn (i) from eqn(ii)

4d = 24

d = \(\frac{24}{4}\) = 6

Thus, the common difference = 6.
