I don't know why you said "possible", but except for this word, the answer is yes. This n0 is the first and minimum value of a range of natural numbers, starting at n0 and never ending.

So your definition says that such and such conditions must be met for all natural values of n starting from somewhere.

The condition might, for example, not be met for n=1, 3, 28, 43, 85 and 113 (I am taking these values from the back of my head), but there is a number, say 121, such that for this number

**and for all natural numbers after it** the condition is met - then your definition applies.

Why they chose to call it n0? Why not? It might seem more obvious to call it n1, as it is the

*first* of the range, but computer folks often number things starting from zero rather than one.

Hope this helps,
