Step 1:

The definition of arithmetic sequence is,

The arithmetic sequence is sequence where the difference between the two successive term is constant

Step 2:

The formula of the nth term of the sequence is,

\(a_{n} = a_{1} + (n - 1)d\)

Where, \(a_{n}\) repreesnts nth term.

\(a_{1}\) repreesnts 1th term d repreesnts the common difference
