SOLUTION: if {{{1/2 }}}{{{1/3 }}}{{{1/4,}}}{{{ 1/5 }}}... {{{1/(n+1)...}}} is an infinite sequence, then t_n= (A){{{1/n}}} n is all natural numbers (B){{{1/(n+2)}}} n is all positive integ

It's not (A), for that would be ... It's not (B), for that would be ... ... It's not (C), for that would be a "two-way" sequence that goes "left and right": ... ... but that contains the undefined term "1/0". So that's not it. If the following were listed I would pick this: I would hesitate to pick (D) for it says nothing about n being and integer. But I would also hesitate to pick (E) However, after thinking about it, I would pick (D) after all because you are given that it is an infinite sequence, so it would not be necessary to say that n is an integer.

Typical provocation.

Keep yourself as far as you can from teachers who give such problems.
