Answer:

common difference is 'b'

Answer 2

Answer:

Answer: The answer is 'a'.

Step-by-step explanation:  

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

a_n=an+b.an=an+b.

Therefore, the (n+1)-th term of the A.P. will be

a_{n+1}=a(n+1)+b.an+1=a(n+1)+b.

We know that the common difference of an A.P. means the difference between two consecutive terms, so

Thus, the required common difference is 'a'.

Hope this helps you!!
