To answer the problem, determine first the common difference by,
 
                                     d = (a18 - a1) / (18 - 1)
 
                                     d = ( 95 - -7) / (18 - 1) = 6

To solve for the 35th term
 
                                      an = a1 + (n - 1)d
      
                                     a35 = -7 + (35 - 1)6 = 197

Therefore, the 35th term is 197.
