Question

If r is a natural number, then the successor of r is

Answer 1

Answer:

odd number

Step-by-step explanation:

Given n is an even natural number

n=2p

Successor of n=2p+1

Predecessor of n=2p−1

Product =(2p+1)(2p−1)

             =2p(2p−1)+1(2p−1)

             =4p  

2

−2p+2p−1

             =4p  

2

−1

             =2(2p  

2

)−1

             =2r−1

represents odd Natural number.
