Question

number of the form 2n+1 where n is any positive integer are always odd number. True or false​

Answer 1

these is true.

let assume n=5 then as per 2n+1 answer=11 which is an odd number..

Answer 2

Answer:

True, as 2 multiplied by any numer is always even. Adding one to any even number will make it odd, so 2n+1 is always odd.

For Example: Let 'n' be 7. So, 2n+1= (2x7)+1

                                                        = 14+1

                                                        = 15

15 is an odd number. This will hold true for any number.
