Let S be the set of positive multiples of three which are greater than one hundred.

Show that S is denumerable.

2. Relevant equations

3. The attempt at a solution

let [tex]\phi[/tex]: [tex]N[/tex] [tex]\rightarrow[/tex] S

be given by [tex]\phi[/tex](n)= 99+3n is a bijection

thus it is denumerable

can someone tell me if that is right? if not can you tell me what i did wrong?
