i think i have posted it but i can't see it on the site

???

3426

let the number be abcd

given:

d=2a

d=c-1 ------>c=d+1

b=c-a

a<6 and odd, so a = 1,3,or5

no two digits are the same

rule out a=5 because then d=10, not possible

let a=1, then

d=2

c=3

b=2, but that would be two digits the same

let a=3, then d=6

c=7

b=4

the number is 3476

thanks

3476 makes sense!
