Every odd number has an odd cube

Odd numbers can be represented as 2n+1.

{2n+1:n ϵ W} or

{1,3,5,7,……}

Here, n belongs to Z because the question says that it is a positive integer and the cube.

Answer 2

Step-by-step explanation:

Heya user ✔✔✔

Here is ur ans⏏⏏

Even no are those no which have the 2 digit gap in there sum like,1 ,2 ,4 etc.

Same

Odd no are those no which are written as (2n+1 ) in sets form

Now roster form is

(x:x <=2n+1, where E belongs to W and N )

Both

✔✔Here we not take Z means Intergers because intergers are the no which is taken in both no as well as positive and negative too both

✔✔But the que is of positive no so we take all the positive no.
