We are to find the common difference of an A.P. if its n-th term is given by (an + b).
The n-th term of the A.P. is
{tex}a_n=an+b.{/tex}
Therefore, the (n+1)-th term of the A.P. will be
{tex}a_{n+1}=a(n+1)+b.{/tex}
We know that the common difference of an A.P. means the difference between two consecutive terms, so
{tex} {common difference},~d=a_{n+1}-a_n=(an+a+b)-(an+b)=a.{/tex}
Thus, the required common difference is 'a'.
