Determine first the common difference (d) of the arithmetic sequence using the given terms,
                             d = (a17 - a6) / (17 - 6) 
                               d = (113 - 36) / 11 = 7
Using the 17th term, 113, we get the value of a23 by,
                             a23 = a17 + (23 - 17) x 7
                                    a23 = 113 + 42 = 155
Thus, the 23rd term is 155.
