Wrong answer, suppose n = 6, a = 1, m = 9.

n = 2m × k (given) , if k = 1 and m = 2, then n = 4. m is NOT divisible by m. So, it is not sufficient as well.

I think statement 2 is insufficient as well: if 2m is divisor of n then let's say that m = n = 3 > 6/3 = 2 let's say, in addition, that a = 1 then 3 is not divisor of 9 (3²).
