1 isn't a prime number, and it didn't say where it started. u just assume it
My bad. Forgot about the prime part. Hmm so u were supposed to start at 2.

I actually looked at all four answers and only one of them correctly fit in the sequence. The three others were out of place (either too small or too big). Dno, prob wulda got that wrong.

Yer. By definition 1 isnt either.

Prime no. = number that can only be divided by one AND itself [1 can be divided by 1 or itself, as they're the same]
Composite number: has factors other than 1 and itself
