Answer 2

a)  

  successor: 345 + 1 = 346

  predecessor: 345 - 1 = 344

b)

  successor: 7886 + 1 = 7887

  predecessor: 7886 - 1 = 7885

c)

  successor: 23567 + 1 = 23568

  predecessor: 23567 - 1 = 23566

d)

  successor: 56789+ 1 = 56790

  predecessor: 56789 - 1 = 56788

d)

  successor: 64574 + 1 = 64575

  predecessor: 64574 - 1 = 64573
