Teacher wrote a number on board.A student told the number is divisible by 31.Then another student told it is divisible by 30,the next student told it is also divisible by 29...thus the last student told the number is divisible by 2.Then Teacher said,"Of all this statement two consecutive statements are wrong".Find those......... ;)

29,2
If it is not, then the number is divisible by $30$ and thus by $2$.

(16,17). As $16$ is the greatest power of 2 and $34$ doesn't divide $31!$
