2. Is there any natural number that has no predecessor?

3. Is there any natural number that has no successor? Is there a last natural number?

Answer:

**1. **

19

predecessor =

successor =

- 1997

predecessor = 1997 – 1 = 1996

successor = 1997 +1 = 1998

- 12000

predecessor = 12000 – 1 =11999

successor = 12000 +1 = 12001

- 49

predecessor = 49 – 1 =48

successor = 49 + 1 = 50

- 100000

predecessor = 100000 – 1 = 99999

successor = 100000 + 1 = 100001
