Answer:
Step-by-step explanation:
first term = a = 352
Common difference = d = second term - first term
                                   = 345 - 352
                                    = (-7)
nth term = a + (n-1)*d
43rd term = 352 + (43-1)*(-7)
                  = 352 + 42 *(-7)
                   = 352 - 294
                   = 58
