Answer:
a) P(n) is true for all 'n' in the set ; { 0,2,4,6,8 ….. }
b) P(n) is true for all 'n' in the set ; { 0,1,2,3,4,5 ............ }
Step-by-step explanation:
a) As P(0) is true 
we will assume that 
- P(2) is true
- P(4) is true 
- P(6) is true
this simply means  that ;  P(n) is true for all 'n' in the set
{ 0,2,4,6,8 ….. }
b) since P(0) and P(1) are true 
we will assume that 
also P(1) and P(2) are true
we will assume that
Also from the previous answers it can be seen that P(2) + P(3) is true
we will assume 
This simply means that P(n) is true for all 'n' in the set
{ 0,1,2,3,4,5 ............ }
