I'm a 4 digit number with no 2 digits the same.
My ones digit is twice my thousands digit and 1 less than my tens digit.
My hundreds digit is the difference between my tens digit and my thousands digit.
My thousands digit is an odd number less than 6.
What number am I?

XXXX
axx(2a)
a(ba)b(2a)
and 2a=b1
so a cannot be 1 as that would make the hundreds digit the same as the ones
if a is 2, then 2a=4, and b=5, and the thousands digit is also4.
if a is 3, then 2a=6, and b=7, and thousands is 4 (73)
number is 3476
lets see if there are others.
if a is 4, 2a is 8, and b=9, and ba is 5: solution 4598
a cannot be greater than 4, as the ones digit has to be twice a.
SO, two solutions: 3476 and 4598
check all this.
