The arithmetic sequence is 12.1, 17.2, 22.3, 27.4,......

The first term .

Find the common difference by subtracting successive terms.

The common difference (d) is 5.1.

Find the nth term, so using the nth term formula: .

                 (Substitute , and d = 5.1)

Distibute terms using distributive property: a(b – c)= ab – ac.

Apply commutative property of addition: a + b = b + a.

                                (Subtract: )

Find the 10th term in the sequence.

                          (Substitute n = 10)

                                   (Multiply: )

                                         (Add: 51 + 7 = 58)
