If n is a positive integer, what is the tens digit of n?

(1) The hundreds digit of 10n is 6.

(2) The tens digit of n + 1 is 7.

from (1), we know the tens digit of n has to be 6 because what 10n does is
just moving the tens digit to the hundreds digit => suff

from (2), we know for example 69+1 = 70 , and 70+1 =71, therefore undecided => insuff
