544-35 = 509
509-35 = 474
474-35 = 439
439-35 = 404 ' so 404 is the answer.
509-35 = 474
474-35 = 439
439-35 = 404 ' so 404 is the answer.

As you can see last digit of each number comes alternatively like 4, 9, 4, 9 so then obviously we get last digit as 4 for next number.

544= 54, 4
509= 50, 9
474= 47, 4
439= 43, 9
404= 40, 4
Then the ans is 404.
509= 50, 9
474= 47, 4
439= 43, 9
404= 40, 4
Then the ans is 404.

Another logic is,
5+4+4=13
5+0+9=14
4+7+4=15
4+3+9=16
4+0+4=8
5+4+4=13
5+0+9=14
4+7+4=15
4+3+9=16
4+0+4=8

544= 54,4 =50-4=50,
509= 50, 9 =50-3=47,
474= 47, 4=47-4=43,
439= 43, 9=43-3=40,
Then, 404= 40 -4; 404 is the ans.
509= 50, 9 =50-3=47,
474= 47, 4=47-4=43,
439= 43, 9=43-3=40,
Then, 404= 40 -4; 404 is the ans.

It is a subtraction series: every number subtracted with 35.
So 439-35=404.
So 439-35=404.
