Step 1: Write the sequence from the given data and identify the first term in the sequence, call this number a.

Step 2: Calculate the common difference(d) of the sequence.

Step 3: Find the term position ( n )

            EXAMPLE: 2,4,6,8,10….in AP

            First term 2, term position (n) = 1

            Second term 4, term position (n) = 2........

            ......... 30th term, term position (n) = 30.......


Step 4: Substitute all the values in the arithmetic formula

            [FORMULA: Tn = a + (n - 1) d,

            where Tn = nth term and a = first term. Here d = common difference, n =  

            term position.]

Step 5: Solve for unknown value. (Apply the BODMAS rules)
